Abstract
A disc driving apparatus has two bases. Both bases swing about their parallel shafts provided at the same side of the bases between positions where the bases chuck a disc-shaped recording medium and positions where they release the medium. A member for rotating the medium is provided for one of the bases, and another member for connecting the medium and the member in order to rotate them together is provided for the other of the bases. The disc driving apparatus also has a pickup for accessing the medium, a chucking mechanism for chucking the medium, a pickup moving mechanism, and a locking mechanism. The pickup can be moved in the radial direction of the medium. The pickup moving mechanism moves the pickup in the radial direction of the medium when the chucking mechanism releases the medium. The locking mechanism locks the movement of the pickup after it is moved to a specified position by the pickup moving mechanism.
