OPIC Light Detector
OPIC Light Detector for DVD-ROM/DVD Player (2X Speed)
General Description
SHARP's IS1640 is OPIC light detector for pick-up of
DVD-ROM/DVD player which is expected as next
generation media.
It is also applicable to 2X speed DVD-ROM/DVD player.
It has sensitivity switching terminal which enables to read
both 1-layer disc and 2-layer disc.
