1. GENERAL INFORMATION
The CDM 12.1 is a modular CD-mechanism, using a 2-stage, 3spot system. It contains the following modules
- a lightpen with holographic lightpath
- the actuator
- the disc motor : a DC-motor with a turntable preparedfor 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 needsto be flexible :
- suitable for 12 and 8 cm. discs according to the REDBOOK standard
- limited size
- applicable in horizontal and vertical position
- optional accessories are available, e.g. tray loadingmechanism, suspension, clamping device, ornamental plate
- wide temperature range
- prepared for a variety of approbation/safety standards

POLARITY OF ACTUATORS/MOTORS
Sledge motor : A positive voltage on the marked terminal(DOT: see fig. 13), relative to the unmarked terminalwill make the sledge move inwards.
Disc motor : A positive voltage on the terminal with thered mark (see fig. 13), relative to the unmarked terminalwill 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 moveinwards.
Focus actuator : A positive voltage on FOCUS+ (see fig.4), relative to FOCUS+ will make the objective lens moveup.

5. STANDARDS
The CDM 12.1 has been designed to comply with safety standardsof various countries. However, since its approval depends onthe application, this unit is not approved as a unit.
It is prepared for the following standards
UL1270UL1409CSA C22.2 No. 1-M90
6. HANDLING INSTRUCTIONS
- Storage in dusty, high temperature and high humidity environments should be avoided.
To avoid damage to the LOGU by electrostatic discharges,measuring equipment and operators sho\lld be grounded duringhandling.
Contamination of the objective lens will influence theperformance. Avoid fingerprints on the lens, handle the mechanism in a clean environment.
The actuator with lightpath has been adjusted carefullyduring manufacturing. Avoid touching this part 11 Do notdisassemble or readjust 11
- Please keep the short circuit clip on the flexfoil mountedas long as possible. Remove just before installing the CDM12.1 in his final application to avoid the risk of damage byelectrostatic discharges.
- Fast heating up (e.g. by bringing the mechanism from a coldplace into a warm and humid room) can result in moisturecondensating on the lens, thus influencing the playability fora certain time. Before checking the performance the mechanismshould stabilize for at least 4 hours.

1. GENERAL INFORMATION
The L1210 is an assembly, consisting of a CDM 12.1 mechanism and a traytype loading mechanism, including the suspension, the damping and theclamping parts (see fig.1).For specific information on the CDM 12.1 mechanism itself, please refer tothe papers adressing this item.
The assembly is designed for 12 and 8 cm. discs according to the RED BOOKstandard. It is applicable only in horizontal position.
The assembly is intended to be used in Hifi (low and middle class) homeapplications. Because of the diversity in applications, different versionsare available.

3. APPLICATION INFORMATION
A. Application conditions
The figures mentioned in this paragraph are valid for the L12l0 used
with the recommended circuit diagram (see CDM 12.1).
Operation :
Temperature range (functional with
discs according to the RED BOOKstandard) 5 to 55 ·C
Temperature range (full
specification) 15 to 50 ·C
Humidity range (functional with
discs according to the RED BOOKstandard) 25 to 90 % RH
Humidity range (full specification) 25 to 75 % RH
Storage (recovery time of 4 h) :
Temperature range .....................•........... -25 to 55 ·C
Exposure 48 h in 70 ·C
Humidi ty range 5 to 95 % RH
Position for usage :
Horizontal (turntable up) +/- 10 deg(all directions)
Horizontal (upside - down) Acceptable for
service purposes.A standard disc
will play. There
is no garuntee on
the specificati~on.
B. Plavabilitv
Criteria No track loss
No audible mutes
Tests are performed with the testdisc SB0444, SBC444A, 150~ eccentri
city disc.
Note :
The skew discs (see page 4) can be used without the disc touching any
of the stationary parts of the loading mechanism.
C. Mechanical noise
Test disc Burn-in
During play Max. 36 dBA
During jump and search Max. 52 dBA
Loading noise Max. 73 dBA
(excluding technical clicks) Max. 53 dBA
Rattling noise ...........................•....... Not allowed
Note : The L12l0 must be measured in a free field
(anechoic room). Hard noise reflecting materials in the direct
environment are not permitted.
The L1210 is to be fixed with his suspension points on a steel
plate (0.8 x 250 x 400 mm). This plate is supported by a foam rubber,
thickness at least 20 mm. The measuring microphone is to be placed100 mm. above the centre of the turntable.
The ambient noise is maximum 22 dBA.

O. Shockresistivitv durinq transport
Shocks (on the mechanism) Max. 60 g during 6 msec3 times 6 directions
Bumps (on the mechanism) .•........... Max. 40 g during 10 msec500 times 6 directions
E. Shocksensitivitv in application
Testdisc ..••..............•........... Burn-in
Shocks :

Criteria ....................•......... no audible mute
Notes :
- Definition of axes
Z-axis : parallel with the shaft of the disc motor
X-axis : parallel with the loading direction of the disc
Y-axis : perpendicular to the X-Z plane
- The L12l0 must be fixed to the testing table.
F. ESO
20 kV in application
14 kV during handling
H. Handlinq instructions
- Storage in dusty environments should be avoided.
- To avoid dammage of the LDGU by electrostatic discharges. measuring
equipment and operators should be grounded during handling.
- Contamination of the objective lens will influence the performance. Avoid
fingerprints on the lens, handle the mechanism in a clean environment.
- The actuator with lightpath has been adjusted carefully during manufactu
ring. Avoid touchin2 this part I1 Do not disassemble or readjust II
- Safety : The laserbeam may damage the human eye. Avoid that people can
look directly or indirectly into the objective lens (CLASS 1 LASER).
- When the unit is not yet connected to the electronics, voltages over 300
V should be avoided (special attention for static charges 11), the diodesmay get damaged.
- 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 theperformance the mechanism should stabilize for at least 4 hours.

2b) Mechanical drawing (high mounting applications)
- The assembly can be delivered with the CDM mounted in the loadingassembly or not. However, if the mechanism is mounted in the loadingassembly, it is impossible to connect the necessary wire assembliesto it. So in this case, the CDM 12.1 should be a version with wires
to avoid unwanted extra handling.
- Two chassis are available: one for high mounting applications, onefor low mounting applications (see fig. 2a and 2b).
- In case of a high mounting chassis, an optional HF-preamplifierboard is available.
- For the choice of the w~r~ng for the CDM 12.1 and for the loadermotor and switch, different lenghts are available on request.
