The second CD player developed as a high-end model of the CD-63.
The pickup section is equipped with an ultra-compact mechanism that drives an original ultra-compact laser pickup with a linear motor.
A linear skating mechanism is adopted for the disk mounting part, and the whole disk tray part is pulled out by the switch, the disk arrives, and it is fixed by the unique disk clamp method.
In this disk clamp method, a precise machining spindle and a unique magnet disk clamper realize a reliable hold.
We have adopted our own fully balanced swing mechanism for the mechanism.
It is equipped with two 8-bit microcomputers and controls the servo system, program system and control system.
A specially developed error collection circuit has been adopted to obtain high error correction capability.
The digital filter LSI reduces the effect on the audible band that cannot be avoided with a conventional multi-stage analog low-pass filter.
I for display, key search, communication between microcomputers, etc.2The CBus system allows two microcomputers to efficiently handle independent functions, so that most of their capabilities can be devoted to the servocontrol required for high-quality sound reproduction.
