Abstract
A disc drive includes a linking arm, which is rotatably supported on the side plate of a top base by a supporting shaft. The linking arm includes a connecting pin, which is engaged with a bottom base. When the top base and the bottom base approach each other and a disc is clamped, the linking arm rotates clockwise. The rotation of the linking arm is converted to a rotation in a horizontal plane, and the power obtained after the conversion is used for the operation of pressuring the clamp or other operations.
