摘要： A disk drive having an anti-shock structure is provided. The disk drive includes: a base member; a spindle motor supported by a spindle motor support formed on the base member, the spindle motor rotating a data storage disk; an actuator rotatably coupled to an actuator pivot supported by a pivot support formed on the base member, the actuator moving a read/write head to a position on a recording surface of the disk; and slots formed in the base member around the circumference of each of the spindle motor support and the pivot support, the slots for partially controlling the stiffness of the base member. The slots include a first slot formed on a circumference region of the spindle motor support near the pivot support, and a second slot formed on a circumference region of the pivot support opposite to the spindle motor support. Due to the structure of the disk drive, the spindle motor and the actuator pivot are inclined in the same direction when an external impact is applied. Therefore, a collision between the head and the disk, i.e., a head slap, is unlikely to occur, thereby minimizing damage to the head and the disk caused by the head slap.
