GENERAL INFORMATION The CDM 12.1 isamodular CD-mechanism, usinga2-stage, 3 spot system. Itcontains thefollowing modules - a lightpen withholographic lightpath - the actuator - the disc motor :a DC-motor withaturntable prepared for magnetical clamping,equippedwithaspring cone - the frame withthesledge drive - the foil with thelasersupply It is suitable forawide variety ofapplications :e.g. standalone players(miniandfull size), CD-RCR applications, and even home CD-ROM systems. To cope with thisbroad application range,theCDM 12.1 needs to be flexible : - suitable for12and 8cm. discs according tothe RED BOOK standard - limited size - applicable inhorizontal andvertical position - optional accessories areavailable, e.g.tray loading mechanism, suspension, clampingdevice,ornamental plate - wide temperature range - prepared foravariety ofapprobation/safety standards APPENDIX 1 APPENDIX 2PPN 13Motor Data RF310T 11400Motor Data Page 26 Page 27 CDM 12.1 SPECIFICATION CDM 12.1 SPECIFICATION Page1
