Optical head and optical disk drive unit therewith

摘要

The head (60) has a laser diode emitting light to an optical disk. A light turning mirror (5) reflects and deflects the light emitted from a photo-diode. A light-raising mirror (8) reflects and deflects the light reflected by the turning mirror in direction of the disk. A part of the light-turning mirror is disposed inside a window portion of a cartridge which houses the optical disk. An independent claim is also included for an optical disk drive unit.
