Embodiment Construction

[0034] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0035] The recording medium loading and unloading device 1 of the present embodiment is a device for supplying the holographic recording medium to an optical region for writing information on or reading information from the holographic recording medium, for example, figure 1As shown, there are: a cartridge holder 2, which transports a cartridge C formed by storing a holographic recording medium in a case between a predetermined loading position and an unloading position; and a screw 4, which supports the cartridge holder 2 movably. , and the cartridge holder 2 is moved between the loading position and the optical region; the frame member 6 forms a part of the body (housingg) that supports the cartridge holder 2 and the screw 4. In addition, the body forms a closed space for accommodating the cassette bracket 2 , the spiral 4 , and the optical region in a state of blocki...

Abstract

The present invention provides a recording medium loading and unloading device for loading and unloading a recording medium in the form of a cassette accommodated in a case and optically recording information. The recording medium loading and unloading device (1) includes: a body that has an insertion opening (10) for inserting a cassette (C), and forms a door (12) that can open and close the insertion opening (10) to cover the outside. A closed space for light; a gate opening mechanism (90), which is arranged in the body, opens the gate (83) that can be opened and closed on the shell of the box (C), so that a part of the recording medium is exposed from the shell. The gate opening mechanism (90) opens the gate (83) only when the insertion port (10) is closed by the door (12).

Description

technical field [0001] The present invention relates to a recording medium loading and unloading device for loading and unloading a recording medium on which predetermined information is recorded, and more particularly to a recording medium loading and unloading device for loading and unloading a recording medium for optically reading and writing information. Background technique [0002] Currently, recording media such as FD (Flexible Disk), MD (MiniDisk), CD (Compact Disk), and DVD (Digital Video Disk) are widely used as a medium on which a large amount of data is recorded. Among such recording media, there is also a recording medium in the form of a cartridge housed in a case. In this case, a shutter that is openably and closably provided in the case is opened to expose a part of the recording medium from the case. The exposed portion is read or written to the recording medium. [0003] With respect to the information reading or writing of such a cartridge-type recording...
