Disk recording/reproducer and method for fixing pickup of disc recorder/reproducer

摘要

A disk recording or reproducing apparatus includes, on a chassis (1), a pickup (2), which is moved while emitting a laser beam onto a signal surface of a disk (7), and a pair of guide shafts (4) and (40) for guiding the movement of the pickup (2). One guide shaft (4) is fitted to the pickup (2) with a fewer play than the other guide shaft (40). Both ends of the guide shaft (4) fitted to the pickup (2) with a fewer play are supported by support members (5) and (50) mounted on the chassis (1), respectively, and further, a cutout (52), into which the guide shaft (4) can be inserted, is formed on a side of at least one support member (50). A pressing member (9) including an abutting piece (90) is provided for preventing the guide shaft (4) from slipping off from the cutout (52) in the vicinity of the support member (50) having the cutout (52) formed thereat on the chassis (1).
