Abstract
A disk drive including a turntable for holding and rotating a disk, a pickup for reading information carried by a signal from the disk and/or recording information carried by a signal to the disk by moving the pickup in a radial direction of the disk that is held and rotated by the turntable, and a feed motor for moving the pickup. A drive gear section, which engages a rack of the pickup, is integrally formed with a rotor of a sled motor. An axis of rotation of the sled motor is disposed parallel to an axis of rotation of the turntable.
