Abstract
An optical disk apparatus according to the present invention includes a spindle motor that rotates an optical disk on whose information recording surface a plurality of addresses is recorded, an optical pickup that records/reproduces an information signal on/from the information recording surface of the optical disk rotated by the spindle motor, an strobe light-emitting unit that irradiates a label surface of the optical disk with light, and a control unit that causes the strobe light-emitting unit to emit light based on an address selected from the plurality of addresses as a reference address and a reference signal readable from the optical disk.
Claims9
An optical disk apparatus comprising:
- a rotation driving unit that rotates a recording medium on whose information recording surface a plurality of addresses is recorded;
- an optical pickup that records an information signal onto and plays back the information signal from the information recording surface of the recording medium that is rotated by the rotation driving unit;
- a light-emitting unit that irradiates a label surface of the recording medium with light;
- and
- a control unit that causes the light-emitting unit to emit light based on an address selected from the plurality of addresses as a reference address and a reference signal readable from the recording medium.
An emission control method comprising the steps of:
- rotating a recording medium on whose information recording surface a plurality of addresses is recorded;
- recording an information signal onto and playing back the information signal from the information recording surface of the rotated recording medium;
- irradiating a label surface of the recording medium with light;
- and
- causing a light-emitting unit to emit light based on an address selected from the plurality of addresses as a reference address and a reference signal readable from the recording medium.
