Abstract

PURPOSE:To record and reproduce without a focus-servo by recording and reproducing by holding a distance between an image-forming lens system and a flexible optical disk. CONSTITUTION:A stabilizing plate 3 of an almost square shape with a prescribed thickness is provided at a position below a disk 1, and an air around the disk 1 flows from an inner circumference to an outer circumference with the function of a centrifugal force by the rotation of the disk 1. Since the disk 1 and the stabilizing plate 3 are closely provided, an air stream is generated, so-called, an air-bearing is formed between them, and a stable rotation with a minimized surface swing can be obtained. Since a recording and reproducing of information is executed by protruding a slider 5 from a window hole 4, the stabilizing plate 3 functions as a disk energizing means, and a distance between the slider 5 and the disk 1 is stably held. Thus, the good recording and reproducing can be executed without the focus-servo.
