Embodiment Construction

[0072] figure 1 It is an external oblique view of the surface side of an optical storage device according to an embodiment of the present invention, figure 2 It is a perspective view of the appearance of the back side. A magneto-optical disk device using a 3.5-inch magneto-optical disk cartridge is shown as a specific example.

[0073] In front of the optical storage device, a front frame 10 is attached. Thus, the door 10b is mounted rotatably in accordance with the insertion or extraction of the disc cartridge, and is energized by an unillustrated spring in the door closing direction.

[0074] In addition, the eject button 10a instructs the removal of the disc cartridge to perform automatic ejection. The manual out-of-box hole 10d is used for inserting the pin when the source is cut off or during inspection or failure. Drain the media. LED10C shows the operating status of the device by emitting light.

[0075] The driver base 20 is provided to embed the panel frame 10 ...

Abstract

The inveniton provides a small, lightweight and highly reliable optical memory, an optical device is arranged directly, through a positioning block, on a drive base mounting a mechanism for accessing an optical memory medium. A device having high elevation is arranged outside a part of drive base where a cartridge holder is contained, and a concave section is formed from upside surface to underside surface of outside a part of drive base under containing cartridge, thus first and second containing sections are formed. A fixed optical unit is arranged at the first containing section where light projector, optical assembly and optical detector are mounted. An ejection motor unit is arranged at the second containing section. The overall height is set as low as about 17mm in a state where a cover and a printed board are fitted, thus the device can be mounted in a thin portable computer.

Description

technical field [0001] FIELD OF THE INVENTION This invention relates generally to optical storage devices, and more particularly to an overall device configuration for making an optical storage device into a compact and lightweight device. Background technique [0002] Optical discs have emerged as core storage media in the rapid development of multimedia in recent years, and are usually accommodated in portable disc cartridges. [0003] Furthermore, the disc cartridge is loaded into the disc device, and the optical head performs information access to the disc. [0004] Currently, an optical disc device is used in a state of being externally installed in a computer via a SCSI interface. The external dimensions of the 3.5-inch optical disk device unit taken out from the external locker (Locker) are 1-inch high, about 25.4 (height) x 101.6 (width) x 150 (depth) mm (plus an accuracy of about ±0.5mm) Error), its weight is about 470g. In addition, the external dimensions of th...
