Embodiment Construction

[0051] Such as figure 1 As shown, according to one embodiment, a removable, recordable optical storage box 112 includes a rotatable, writable storage disc 114 surrounded by a box body having a substantially rectangular side wall 122 The upper wall 116 and the lower wall 118 are connected. In one embodiment, the medium is an InSbSn phase change medium of the type used by Kodak, which is related to a 14-inch optical write once read many (WORM) disc product. Examples of suitable media are described in U.S. Patent Nos. 4,960,680 and 527,1978. This medium is suitable as the first surface medium. This medium is basically panchromatic or broadband, so that it can be used with a certain range of laser frequencies (for example, from 400 nm or less than 1100 nm or greater wavelengths), making it possible for the present invention described here to work with short-wave lasers ( For example, a blue laser) can be used together to achieve a smaller spot size (and thus a higher data density) wi...

Abstract

A user-removable optical data storage system is provided. A rotatable first surface media is enclosed within the cartridge. Although the size of the box is relatively small, such as 35mm×35mm×3mm, it provides a relatively large data capacity, such as 0.25GB or more. Preferably, the cartridge substantially seals the data surface of the medium when the cartridge is withdrawn from the drive, and at least a portion of one surface of the cartridge is automatically exposed to the objective lens of the optical arm when said cartridge is inserted into the drive. Tracking involves rotating the optical arm about an axis parallel to the axis of rotation of the platter. Focusing may include rotating the arm about an axis parallel to the disc surface.

Description

Technical field [0001] The invention relates to a removable optical storage medium, and more particularly to an optical storage disc box. Background technique [0002] Various disk-shaped optical storage media have been developed to store various types of digital data in a manner that can be easily removed from the read / write or drive device designed for them. Current common examples (generally read-only) include compact discs (CD) and digital versatile discs (DVD). Although these examples have been very successful for specific purposes, such as storing data on a personal computer (PC), or storing music or other audio or video information, such as animation, they have been confirmed due to application, historical or other reasons. The device is not very suitable when the optical storage medium is preferably small in size. One of these uses is Personal Electronic Device (PED). The general size, shape, and weight of personal electronic devices are suitable ...
