RECORDING/REPRODUCING APPARATUS AND DISK CARTRIDGE

摘要

PROBLEM TO BE SOLVED: To satisfactorily reduce disk surface vibration in a recording/reproducing position with a simple constitution of a main stabilizing member and an auxiliary stabilizing member that cause Bernouilli effect to act. SOLUTION: A disk surface of an optical disk 1 is divided into two regions S1 and S2 by a straight line A being close to a a movement line R for an optical pickup 4 to scan in the surface of the optical disk 1 and passing in the vicinity of a center of the optical disk 1. At least one auxiliary stabilizing member 6 is arranged separately from the the main stabilizing member 5 and in the region S2 positioned on the downstream side of an optical disk rotational direction in an optical pickup 4 out of two regions S1, S2.
