ABSTRACT:
A disc drive apparatus is composed of a disc carrying mechanism, a turntable (1), a pickup unit (2), a pickup transport mechanism, a reversible motor (7), a first transmission system (8A), a second transmission system (8B), and a transmission route changing mechanism. The pickup transport mechanism is further composed of a screw shaft (5) and a driven body (6) linking to the screw shaft (5) and the pickup unit (2). The driven body (6) moves reciprocally and linearly in a transport direction of the pickup unit (2) by reversible rotation of the reversible motor (7), and moves with being accompanied by the pickup unit (2) within a movable range (L) of the pickup unit (2), and moves independently out of the movable range (L). The transmission route changing mechanism conducts to change the transmission route linked to the reversible motor (7) from the first transmission system (8A) over to the second transmission system (8B) when the driven body (6) is moved independently out of the movable range (L) while the pickup unit (2) is stopped at one end of the movable range (L).
