Provided is an optical scanning element that includes mirror unitand movable unitincluding mounting uniton which mirror unit is mounted and which is configured to be rotatable. Mirror unitincludes: a dielectric multilayer film that reflects a part of incident light while transmitting the remainder of the light; and a first substrate on one surface of which the dielectric multilayer film is formed, and which transmits the remainder of the light passed through the dielectric multilayer film. Mounting unitincludes a through-hole at a portion facing the dielectric multilayer film.

A transportation bodyfor a flexible optical diskhas flexibility, and includes a rotation stabilizing boardhaving a disk-shaped form, an optical disk alignment unitinstalled in the central part of the rotation stabilizing board, and a spacerinstalled on a surface of the rotation stabilizing board. A combination of the transportation bodyand the optical diskcan be treated as an equivalent of a conventional optical disk having rigidity, by transporting the flexible optical diskplaced on the transportation bodyand by recording/reproducing information onto/from the flexible optical disk.

Transportation body for flexible optical disk, optical disk transportation apparatus, and optical disk transportation method

To develop optical discs stored while being stacked and to load them to a plurality of recording/reproducing devices simultaneously. Trays for mounting optical discs are stacked to configure an optical disc transportation body, and the portions being exposed without overlapping when the stacked trays are viewed from the stacking direction are utilized as tray operation portions for handling. Supporting portions abutting against the tray operation portions inherent to respective trays in one to one correspondence are fixed with an interval in the vertical direction to the frames configuring a tray distributing/holding portion. The tray operation portion of each tray is held by the supporting portion at each position by moving the optical disc transportation body downward along the frames, and intervals corresponding to the arrangement pitch of recording/reproducing devices are formed between respective trays.

[Problem] The problem is to provide a system with a large capacity as the recording and regenerating apparatus through piling optical disks and stocking the piled optical disks compactly. [Means to solve the Problem] An optical disk recording and regenerating apparatus to make a holding means, which includes an optical disk sucking part to suck an upper surface of an optical disk, and a partition sheet sucking part to suck a partition sheet by sucking a held area of the partition sheet and which sucks and holds at least one of the optical disk and the partition sheet, move to an optical disk drive from a tray loaded with a plurality of the optical disks which are piled through the partition sheet having the held area projecting from an edge of the optical disk and not overlapping with the optical disk when the optical disk and the partition sheet are piled. It may be preferable that the partition sheet includes an optical disk exposing area, and the holding means includes an optical disk sucking part to suck the upper surface of the optical disk in the optical disk exposing area, and a partition sheet sucking part to suck an upper surface of the partition sheet.

Optical disk apparatus

A disk stabilizing plate is disposed oppositely below a thin disk for the purpose of allowing the thin disk to rotate stably, in a recording and reading device that uses a flexible thin disk for recording and reading. The disk stabilizing plate has a movable disk support member, relative to the prescribed rotation condition of the thin disk, that is caused to protrude upward from the surface of the disk stabilizing plate to touch and support the thin disk, or that is drawn downward from the surface of the disk stabilizing plate from the state touching and supporting the thin disk so that the state wherein the thin disk is touched and supported is terminated.
