Integrated unit, optical pickup, and optical recording medium drive device |
| abstract |
The medium of a disk for CD-R is a pigmentation material so readout by a 650-nm laser diode (LD) is not possible. Since CD-R is becoming popular in the marketplace, there are demands for a DVD readout device that is capable of reading CD-R format disks. An integrated semiconductor laser element is created by forming a two-wavelength LD monolithically on a GaAs substrate, and that laser element emits a laser beam that is reflected by a 45° mirror incorporated in a flat package. n If a three-part holographic element is used, and the light-receiving element and an amplification circuit are integrated on a silicon substrate, it is possible to implement a small, light-weight optical pickup with fewer components. |
