The CDM 12.1 is a modular CD-mechanism, using a 2-stage, 3- spot system. It contains the following modules

- a lightpen with holographic lightpath

- the actuator

- the disc motor : a DC-motor with a turntable prepared for magnetical clamping, equipped with a spring cone

- the frame with the sledge drive

- the foil with the lasersupply

It is suitable for a wide variety of applications : e.g. standalone players (mini and full size), CD-RCR applications,

and even home CD-ROM systems.

To cope with this broad application range, the CDM 12.1 needs to be flexible :

- suitable for 12 and 8 cm. discs according to the RED BOOK standard

- limited size

- applicable in horizontal and vertical position

- optional accessories are available, e.g. tray loading mechanism, suspension, clamping device, ornamental plate

- wide temperature range

- prepared for a variety of approbation/safety standards

3. APPLICATION CONDITIONS

Note : With discs according to the RED BOOK standard

POLARITY OF ACTUATORS/MOTORS

Sledge motor : A positive voltage on the marked terminal

(DOT: see fig. 13), relative to the unmarked terminal

will make the sledge move inwards.

Disc motor : A positive voltage on the terminal with the red mark (see fig. 13), relative to the unmarked terminal

will make the disc motor run in clockwise direction.

Radial actuator: A positive voltage on RADIAL+ (see fig.

4), relative to RADIAL- will make the objective lens move inwards.

Focus actuator : A posi tive voltage on FOCUS+ (see fig.

4), relative to FOCUS+ will make the objective lens move up.

5. STANDARDS

The CDM 12.1 has been designed to comply with safety standards

of various countries. However, since its approval depends on

the application, this unit is not approved as a unit.

It is prepared for the following standards

6. HANDLING INSTRUCTIONS

- Storage in dusty, high temperature and high humidity envi- ronments should be avoided.

To avoid damage to the LOGU by electrostatic discharges, measuring equipment and operators sho\lld be grounded during handling.

Mechan;sm with wiring

Contamination of the objective lens will influence the

performance. Avoid fingerprints on the lens, handle the mecha- nism in a clean environment.

The actuator with lightpath has been adjusted carefully during manufacturing. Avoid touching this part 11 Do not

disassemble or readjust 11

- Safety :

people can

lens.

The laserbeam may damage the human eye. Avoid that

look directly or indirectly into the objective

- Fast heating up (e.g. by bringing the mechanism from a cold place into a warm and humid room) can result in moisture condensating on the lens, thus influencing the playability for a certain time. Before checking the performance the mechanism

should stabilize for at least 4 hours.

- Please keep the short circuit clip on the flexfoil mounted as long as possible. Remove just before installing the CDM

12.1 in his final application to avoid the risk of damage by

electrostatic discharges.
