Abstract
PURPOSE:To eliminate the need for an optical head having a long stroke in a focus depth direction or a highly accurate focus servo by applying stable rotation with extremely small surface vibration to a flexible optical disk by a stabilized plate. CONSTITUTION:The stabilized plate 3 with an approximately square shape having a prescribed thickness is arranged on the lower position of the disk 2. When the flexible optical disk 2 is rotated adjacently to the stabilized plate 3, stable rotation with extremely small surface vibration is applied to the disk 2 from the stabilized plate 3. An optical beam is radiated on the disk 3 through a part consisting of a transmissible material of the plate 3 to record/reproduce data. Consequently, an optical head with a long stroke in the focus depth direction can be omitted and highly accurate focus servo can be also omitted.
