@ About & Build Quality @
I bought 300 of these discs and I mainly use them for bootable files for my PC and taking them to work. I bought them because they were so cheap, and on offer. The discs themselves are no thinner than any other CD-R and are not too flimsy. They do have some give and can flex a little bit but they aren't stiff. Dropping them from a few feet onto a laminate floor will not break them but can chip the disc. They are not at all scratch resistant either so sliding them along coarse surfaces or flipping them around in your hands with other CDs will scratch them, and these can be quite large scratches.
The top of the CD has a silver plastic film over the top of it and if you start to scrape away at it, eventually it will come off. However one thing I do like about the top layer is that the there is a lot of space to write things, and there are lines provided for you to write notes and title of the disc. The space available and the Tesco label both appear on the top of the disc.
@ Burn Quality & Playback @
I have had a few bad burns before and all of them were caused by buffer under run failure. Basically the poor build quality of the layer on the disc which the laser will burn to, has mistakes and glitches in the lines where the content is burned to, so the discs can't buffer, and burning over these errors will cause problems with audio on audio CDs and further corrupt files on data CDs.
On CDs that do burn correctly though the playback is quite average. Sound quality is not perfect on audio CDs where bass is flat and tinny with no peaks of high hats which sound hollow and not as sharp as they should. The good thing with Data discs though is that the CDs are fast to access and I have never had any problems with transferring files from the disc to a computer. The discs are able to quickly transfer files without any problems or errors,and I have never had a file that was unable to transfer.
Burning to the discs can be up to 52x but I strongly recommend using a much slower burn. For example, 32x. These discs can do 52x speed burns so they are not lying, but the discs do screw up and fail burns at this speed, and they are not built for it.
@ Overall @
These discs are cheap, and you get exactly what you pay for, low quality build, and low quality playback for audio. If you want these as data CDs for your computer then by all means get them because they are fantastic for this purpose but for audio, these are a NoNo. And regardless of what you want them for: burn them much slower than 52x
If you're going to buy any form of computer accessories, I think in the first place you would go for well known computer manufacturers. Myself, I'm not a technological whizzkid and all I wanted when I bought these blank CDs were to burn a few copies with music so that I could keep them in the car and listen to them when and where. Despite not being re-writable, they may seem a waste but to be honest when they're burnt with different music tracks it's value for money.
A few pointers about the pack.
- Comes in packs of 25
- Disc recording speed is 52x
- CD-R media type
- Disc capacity of 700MB
- Standard recording time of 80 minutes
A pack of 25 is available from tescodirect.com for £3.50 and for 25 I consider that a bargain no matter what the quality.
They do what I want them to do, which is to store music for the car and this is definitely ideal. At 71p a disc I can't complain at quality for money. My advice would be if you want a faster processing disc of better quality, capacity and recording time, fork out a little extra for a more reliable brand. I never expected anything good from these but I bought them for a simple purpose and that purpose is fulfilled with ease.
These are very handy for students who have to submit their work with a CD. I recommend this because I have a friend who often uses them as they have to submit electronic work as well as written work at the sametime and these are so cheap they are ideal for this purpose.
I wouldn't recommend these to people who want it for other purposes e.g. storing images or transferring data. They're nice and simple, cheap, and I still have a load of blank ones left! They may not be up to standard with today's demand of higher memory and processing speed but they do what you need them to do.
I bought 2 packs of 100 and so far only some work i have got a second pc exactly the same and some that don't work on my pc work on the other and also these are terrible for booting from if your like me and have to boot from them stay clear. also another instance was roxio 2010 kept failing and hen when it said it was done i put the disk in and it didn't work.So far i would say my success rate is around 20 percent. Tesco really do need to look into the quality of there .I would go and try to get a refund but there 6 months old. I have also tried some Maxtor ones and there work a treat. Looks like im going to have to get some new ones.These are also the worst discs i have ever used in my life and i would like to advise other people not to buy them.
These days there are hundreds if not thousands of different brands of blank media on the market, and it's no surprise that the supermarket giant Tesco has branded some as there own.
Now the quality of blank media is solely dependent on the ink used in the dye on the underside (the colourful bit that reflects). It is clear after using some Tesco one's that no single ink is used but several different ones, so the quality obviously varies with them. Some burns work perfectly fine in stereos, cars and laptops. Others are coasters (failed burns) and hence useless.
All I can say is you have no guarantee of which batch of these discs you are buying and therefore have no clue as to what ink (and hence the quality of it) is being used so avoid them completely. Stick to the only name worth your time in blank media - Verbatim.
It's been a long time since I've actually needed to use a CD-R, as I normally stick to blank DVD disks regardless of whether I'm burning movie files, photos, personal data, or backing up my hard drive.
But my six year old cousin was given a personal CD player for his birthday. Now I know what you're thinking, most likely the same thing I did. Can you still buy those, and why not just get him an mp3?
Needless to say he wanted one and nothing else would do. So I decided that I would put some of his music on to a couple of CD's for him (naturally nobody thought to buy him an actual CD for his birthday.) He is going though the stage of either loosing items or more commonly breaking them. And because I knew that he would more than likely use it as a Frisbee, or play with it in his sandbox, I wanted to buy the cheapest blank CD's I could find. Enter these Tesco branded 52x media.
I had his music (ranging from children's nursery rhymes, to tracks by Hi-5, Milkshake and others) on my computer ready to go. I would need to split the tracks over two disks. So I inserted the first blank Tesco disc. Nothing happened at first. My disk drive just span the it around and around making strange noises before finally spitting it out around half a minutes later. I tried a second time with the same disk and the same thing happened. So I could only conclude at the time that the first disk out the cake box (or spindle) was faulty. So I put it to one side, and inserted another. "Great" I said, as up popped a dialogue box asking me what I wanted to do. "First one was a fluke" I said again, as I began his burning his first disk at 48x (the fastest Nero would let me).
I was about to phone him and tell him the good news that his music was on the way. That was until I stood up and with greeted with a "Burn Process Failed" error message, while the process had only reached thirty percent. Shaking my head I removed the disk and threw it straight into the bin. Next one went in no problems, and I actually sat at my computer watching the percent bar indicator move from one to one hundred. My computer ejected the disk and I was happy to see the "Successful" message" (I even put it back in just to make sure.)
So far my success rate with the disks was one out of three. So I set about burning the second disk. Every thing looked good, until the burn process failed again, this time at nearly seventy percent. And then AGAIN with another, but this time, the burn process failed at a very frustrating ninety odd percent, just as I was convinced that it had worked.
Thankfully as I was about to throw the entire pack in the bin, the next disk I inserted worked fine and completed the burn process.
I think it should be clear by now with my success rate with the disks that they should be avoided. I don't know why I had such a high failure rate with them, as my disk drive has always been more than happy to play or burn to any brand. Maybe someone else would get on better with them. But from my experience, I can only conclude that they are simply poor quality. I just feel annoyed that I spend so much time doing this for my cousin, because of the faulty disks.
Rather than bin them (as the chances are I would never use them again even if I needed to) I decided to ask Duncan (a family friend) if he wanted them (for free). "Sure." He said happily before asking me what brand they were. "Tesco" I told him. Hmm, I don't think I'm allowed to write what his colourful replay was, but needless to say the disks are now in the bin (less stressful that way).
But lessoned learned and in the end my cousin did get his two CD's (and for the moment they seem to work).
Next time I'll pay slightly more and get a better brand (both Sony and Verbatim have been recommended to me.) I suggest you do the same.
I purchased a pack of tesco 50 CD-R 700 MB 52x for my mac mini and had a 90/% success rate. Then I bought another 50 and none worked. I bought a pack of Sony 48 x and so far all have worked and I have used half of them. I know others who will not use tesco discs. As far as I am concerned i won't buy them again. Tesco must look at the quality of the discs they are making or having made for them. I also have a low success rate with their dvd rw. So I am afraid i have to give tesco a big thumbs down and if you are a mac user a definite no. O and i got the sony from tesco buy one get one free so i bought 2 packs for one. When none of the tesco discs worked i thought i new a new cd writer
I still remember the old days when a single CD from Sony or TDK used to cost around £1 and they used to come in individual CD case. But now you can buy loads of them in a towering stack called 'spindle', and they come cheaper than match-sticks !!
I bouth 25 pack CD from Tesco last year. It was nice small spindle package and CDs were nice silver matt finish with Tesco's name written on it. I have bought cheap CDs from the internet websites, but they come in ugly Red / Purple colors.. But this CDs were better lookwise.
As they are cheap and basic, I did not expect anything extra ordinary out of it. I just wanted to burn some audio CD to play in the car audio, and also use it as temporary media to send photos to my parents. I would not use it to backup photos permanently as it is very easy to get scratches on this, making it unreadable.
Only irritating bit was when I created Ubuntu Linux Live CD on this. May be something is not EVEN about this CD, so it spins frantically in my laptop drive, making my laptop vibrate a lot. This doesn't happen with other Sony or good branded CDs.
But as I said, I was happy with its basic functions and I bought the same 25-pack couple of times from Tesco.
What can I write about Tesco CD'rs. Although lot of people actually says that we should stay away from value CD and DVD's I find Tesco CDrs useful and very solid. I have never been dissapointed.
The most important thing is the price. You get 52 700 MB CDs for as far as I remember 9,99 and thats a bargain. Off course you can invest in Verbatim or TDK disc which are more posh and lets say more expensive but if you have a lot of data to burn every day as a storage drive Tesco's CDs are far more better. 52 CD's thats over 35 GB of data.
You can store lots of pictures, photos, music or even a few homemade movies on one CD. There's lot of opinions that we shouldnt actually use them because they can wear our lasers more than expensive CD's. That may be true although I'm using them for more than two years (since I came here) and I've never had any problems with that.
Anyway it's up to you. I advise you to use them as a storage not to play everyday just in case I've been wrong.
