ABSTRACT:
A disc recorder/player that prevents foreign matter such as dust or the like from adhering to a drive shaft for assuring a highly accurate position control of the movable write and/or read unit. In the disc recorder/player, an electromechanical transducer is used as a drive source provided in a feeding mechanism for an optical pickup to expand and contract a drive shaft installed on the electromechanical transducer, and a dustproof cover unit is provided on a base to cover the top of the drive shaft. When the optical pickup supported on the drive shaft is moved, the dustproof cover unit can prevent dust, having entered when a disc cartridge is introduced into or removed from the disc recorder/player, from adhering to the drive shaft.
