Method of driving optical disc and optical disc drive using the method

摘要

A method of driving an optical disc and an optical disc drive using the method is provided. The method includes rotating an optical disc by a spindle motor, transferring an optical pickup positioned to correspond to the optical disc by driving a sled motor, and decreasing a current supplied to the spindle motor while driving the sled motor.

1. A method of driving an optical disc, the method comprising:
rotating an optical disc having program zones and acceleration regions by a spindle motor driven at zoned-constant linear velocities of which a profile thereof has the acceleration regions, each of the acceleration regions being disposed between and directly contacting adjacent program zones; increasing a linear velocity of the spindle motor throughout each of the acceleration regions; reading data in the program zones in response to the increasing of the linear velocity of the spindle motor; moving an optical pickup positioned to contact the optical disc by driving a sled motor; and, decreasing a current supplied to the spindle motor while driving the sled motor such that a total current supplied to the spindle motor and the sled motor is smaller than or equal to a threshold current, wherein the current supplied to the spindle motor is decreased by an amount equal to a current supplied to the sled motor in response to the sled motor being driven.
