OPTICAL DISC APPARATUS

摘要

An optical disc apparatus regularizes an air flow generated by disc rotation so as to suppress vibration of the disc and prevent lowering of a recording signal quality and reproduction signal quality. Cut-off portions (24, 26) are formed at the upper end of the right and left walls (20, 22) of the frame (10). Both ends of a clamper holder (28) in the longitudinal direction are fixedly mounted onto the cut-off portions (24, 26). At surface portions (28a, 28b) at both sides of the clamper holder (28) sandwiching a clamper (30) where the air flow generated by disc rotation flows out, saw-tooth shapes (32, 34) are formed as rectifiers.
