| 英文摘要 | A laser beam emitted from the laser emission unit (20) is emitted through an objective lens (12) and focused on an optical medium. A reflected beam from the optical medium is returned through the objective lens and a diffraction grating (11) to a signal detection circuit (34) in the laser emission unit. Hitherto, many operating functions have been provided in the optical head (1). However, the present invention provides the laser emission unit in a lens holder (10) and with a plurality functions in the emission unit itself and so the space in the optical head can be reduced. Moreover, the space for the light path both emitted and received is also decreased. Thus, the size of the optical head is extremely reduced and since the optical head can be assembled by a smaller number of parts, the production costs can be decreased. |
