Datasheets for Philips or JVC CD pickups
I'm looking for a datasheet with as much detail as possible on the
optical pickup in the JVC XL-FZ158BK. It's either from Philips or Sony. The actual pickup is a "hologram laser" with 10 pins in a flat package with the hologram part in the cover. What I'm after is really the details of the optical arrangement to identify the photodiode locations. I has a normal edge-emitting laser diode with its beam reflected by a really tiny prism. But I can't visually identify either the monitor photodiode, or the phodiiodes in the PD array. Here is a poor photo: http://repairfaq.cis.upenn.edu/Misc/...oto-diodes.jpg 13,14,15,16 are pads for the laser diode. B is the angled mirror face. A is the flat top of the prism. It is not known what, if anything, is below this. Any information appreciated. Thanks! --- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name AND either lasers or electronics is included in the subject line.
