Patent ID: 7519978

Claim:
A movement adjusting device for adjusting movement of a disc drive which is movable by a mover unit between a first position at which a disc-shaped recording medium is attachable and detachable and a second position at which the disc-shaped recording medium is processed, the movement adjusting device comprising: a guide surface extending along a motion path of the disc drive; a guide member which is provided on the disc drive and contacts the guide surface; a biasing unit which biases the guide member in a direction in which the guide member is pressed toward the guide surface; and a variable unit which increases a biasing force of the biasing unit when the disc drive is near the first and second positions; wherein the biasing unit includes an elastic member which is elastically deformable; and the variable unit increases the biasing force by increasing the elastic deformation of the biasing unit when the disc drive is near the first and second positions, whereby the biasing force is weakened by decreasing the elastic deformation of the biasing unit while moving the disc drive between the first position and the second position.
