Patent ID: 7936652

Claim:
An optical disc apparatus for recording or reproducing video information onto/from an optical disc, by irradiating a laser beam upon said optical disc while rotationally driving said optical disc, comprising: an optical pickup, which is configured to irradiate the laser beam upon said optical disc; a tilt adjustment unit, which is configured to conduct a tilt adjustment through learning of tilt amount; a buffer for storing video information to be recorded or reproduced onto or from said optical disc; a recording/reproducing unit, which is configured to record or reproduce said video information onto/from said optical disc; a temperature detector which is configured to detect temperature; and a control unit which determines whether a relearning of tilt amount of said optical pickup should be conducted or not, upon basis of change of the temperature, which is detected by said temperature detector; wherein said control unit determines whether the relearning of tilt amount of said optical pickup should be conducted or not, upon basis of the change of the temperature, which is detected by said temperature detector, in addition thereto, and further a remaining memory capacity of said buffer.
