Marantz CD-99DR 228,000yen(1988 release)

compact-disk transport put on the market as a compact-disk drive unit of digital-analog-converter loading Integrated-Amplifier PM-95 to combine.

CDM-1 original drive mechanism adopted as representation models including LHH2000 is adopted as a mechanism part. The swing arm supporting a pickup part serves as a dynamic blance type which is a structure contrastive with the usual linear-tracking, and allotted the wait to the rear.
The linear motor is adopted as an actuator and the smooth operation is realized. Moreover, a pickup part has little aberration and has adopted "1 Beam scheme" excellent in the temperature characteristic.

The newly developed automatic servo change circuitry is carried in the servo circuitry, a sensor detects the magnitude of 12cmCD and 8cmCD, and the servo circuitry in a motor is switched automatically.

The toroidal transformer is adopted as a power-source part, and the source impedance fall of the smooth electric power supply to a servo circuitry and a digital circuit is aimed at.

High rigidity die-casting is adopted as a chassis. Moreover, to the sole plate, absent-resonance-ization, such as using die-casting also for a side panel, is attained using the griddle of 3mm thickness.
Moreover, the original ARC (Aluminium Raft Celing) structure is adopted as a top cover, and according to 3 piece structures which cut Raft (the shape of a raft), while increasing the intensity, the oscillation mode was diffused, and the vibration is prevented.

compact-disk file bank FTS which can choose and memorize a favorite track is carried. Thereby, if memory is carried out once, it can file semipermanently.
