Abstract
A disc drive for performing writing information on and/or reading out information from a disc has a head, a movable member, a driving device, a restriction device and a release device. The head writes information on and/or reads out information from the disc. The movable member supports the head. The driving device moves the movable member. The restriction device fixes the movable member in a predetermined position in a moving path of the movable member by using a magnetic attractive force. The release device releases the movable member from the fixed state at the predetermined position by using a magnetic repelling force.
