ABSTRACT:
A disk drive includes a chassis and first and second disk-positioning members mounted respectively on two opposite sides of the chassis. The first and second disk-positioning members have two straight inner portions extending perpendicularly and respectively from the opposite sides of the chassis to define a first distance therebetween, and two outer portions extending inclinedly and respectively from the inner straight portions in such a manner to define a second distance therebetween. The second distance is longer than the first distance. When an optical disk is moved to a reading and/or writing position from a temporary position, the inclined outer portions of the first and second disk-positioning members are spaced apart from the disk to permit smooth rotation thereof.
