Title:
光ドライブにおけるレーザダイオードの寿命の向上
Document Type and Number:
Japanese Patent JP5808831
Kind Code:
B2
Abstract:
A reproducing apparatus for reproducing data recorded on an optical record carrier is provided having an improved lifetime of the laser light source used to read the data. The reproducing apparatus includes a laser driver unit that is adapted to drive the light output of the laser light source to change from a reading mode, in which data recorded in the optical disc is being read for being reproduced, into a laser lifetime extension mode when an operation of reading said data is paused. In the laser lifetime extension mode, the laser light source is driven to emit a pulsed light output, therefore, the amount of time in which the laser light source is on without being needed is reduced and the lifetime of the laser light source is improved.
