Abstract
An optical module has a first light source which emits a first light beam from a first light emission point in a predetermined direction, a second light source which emits a second light beam from a second light emission point in the predetermined direction, and an optical element. The optical element includes a plurality of reflection surfaces for reflecting the first and second light beams, and finally outputting the first and second light beams in the predetermined direction with a separation between the first and second light beams smaller than a distance between the first and second light emission points.
Claims16
An optical module comprising:
- a first light source which emits a first light beam from a first light emission point in a predetermined direction;
- a second light source which emits a second light beam from a second light emission point in the predetermined direction;
- and
- an optical element having a plurality of reflection surfaces for reflecting the first and second light beams, and finally outputting the first and second light beams in the predetermined direction with a separation between the first and second light beams smaller than a distance between the first and second light emission points.
2-16. (canceled)
An optical recording and/or reproducing apparatus for recording information on and/or reproducing information from a recording medium using a light beam, comprising:
- an optical pickup which emits one of two light beams having mutually different wavelengths on the recording medium depending on a type of the recording medium;
- and
- means for processing the information to be recorded on the recording medium prior to supplying the information to the optical pickup, and processing the information reproduced from the recording medium and obtained from the optical pickup,
- said optical pickup having an optical module comprising:
- a first light source which emits a first light beam from a first light emission point in a predetermined location;
- a second light source which emits a second light beam from a second light emission point in the predetermined direction;
- and
- an optical element having a plurality of reflection surfaces for reflecting the first and second light beams, and finally outputting the first and second light beams in the predetermined direction with a separation between the first and second light beams smaller than a distance between the first and second light emission points.
