Abstract
A method for controlling an optical drive to record data onto a disc. The optical recorder has a pick up head for emitting laser onto the disc to record data onto the disc. The method includes adjusting a write power and a write strategy of the optical drive according to a linear velocity of the disc when passing by the pick up head.
Claims10
A method of controlling an optical drive to write data onto an optical disc, the drive comprises a pickup head for emitting a laser to write data onto the DISC, the method comprising:
- adjusting the laser power emitted from the pickup head based on the linear velocity of the disc when the disc is passing through the pickup head.
A method of controlling an optical recorder to write data onto an optical disc, the drive comprises a pickup head for providing energy onto the disc;
- while the received energy of the disc is over a threshold, a mark for recording data is formed on the disc;
- during forming a mark on a data-location on the disc, the drive determines when to start to provide energy based on the write-in strategy before the data-location passes through the pickup head;
- the method comprising:
- adjusting the write-in strategy based on the linear velocity of the disc when the disc is passing through the pickup head.
