Ricoh MP 7163A

Ricoh MP 7163A ... to enable high-speed writing and reading. High-speed writing is handled by the pick-up module incorporating a high power laser and high precision pulse control. The newly developed digital control LSI controls the pulse width with precision boasting 1.5 times of the traditional mechanism, thus allowing for stable writing at high speed. Incorporation of the high-speed rotation type spindle motor gives stable and precise rotation during high-speed writing. The adoption of the high-precision stepping motor for the seeking mechanism enables determination of access position at high precision and high-speed access at 120 ms, while improving the noise level. Improvement in wide band and low noise in the pickup's amplifier unit ensures high-speed reading.
