Abstract: An optical disc drive comprises: a turntable for mounting an optical disc; a driving unit for rotating the turntable; and an optical disc heating means for heating a center portion of the optical disc. In the optical disc drive, an inner circumference temperature of the optical disc is maintained to be higher than a peripheral temperature of the optical disc by at least 50° C. According to this, a growth of a crack generated at a periphery of a hole of the optical disc is restrained thereby to effectively prevent a damage of the optical disc.
