The compact disk player of No. 1 of a Marantz. compact-disk-63B becomes a black model of this opportunity.
The original balanced type swing scheme mechanism is adopted.
Two 8-bits microcomputers are adopted as a servo control.
This has controlled the focal servo, the radial servo, and the turntable servo.
The error collection circuitry of a development is carried specially and the detection error by dirt, dust, etc. adhering to a disk is corrected.
The disk clamp scheme by the ultra-precision machining spindle and an original magnet disk clamper is adopted.
The miniaturization of the pickup is carried out in real g by the original optical system configuration at the same time low power-semiconductor laser realizes a power saving.
The Marantz carries digital filter LSI developed uniquely, and has changed the sampling frequency into 176.4kHz, 4 times. The bessel type low pass filter which was excellent in the phase response is adopted as the filter which cuts it.
The I2CBus scheme is adopted as the communications between a display device, key search, and a microcomputer etc.
This is attaining the increase in efficiency of the microcomputer functionality.
An all playback, a random access special NetWare program, a deletion playback special NetWare program, etc. are possible.
