Patent ID: 6901039

Claim:
An optical drive system, the optical drive system adapted to write data at a substantially linear density on an optical disc, the optical drive system further adapted to change a linear velocity while writing to the optical disc to reduce a likelihood of a buffer under-run condition, the optical drive system comprising: a spindle, the spindle adapted to rotate the optical disc, the spindle including a servo, where the servo controls a rotational speed of the spindle; an optical pick-up adapted to write data to the optical disc, where the optical pick-up is also adapted to detect a signal relating to a linear velocity of the optical disc at a position on the optical disc adjacent to the optical pick-up; and a controller, the controller communicating to a host computer to receive data to be written to the disc, the controller communicating with the optical pick-up to transmit the data to the disc, the controller further adapted to control the rotational speed of the spindle such that the linear velocity of the position on the optical disc adjacent to the optical pick-up may be dynamically changed while the optical pick-up is writing the data to the disc.
