Abstract

The invention discloses a portable and stretchable compact disc-read only memory (CD-ROM). The portable and stretchable CD-ROM comprises an inner shell, a middle shell, an outer shell, a base, a fixing cap, a switch, a universal serial bus (USB) interface and an optical disk fixing device. When using the portable and stretchable CD-ROM, a user places an optical disk on the optical disk fixing device, stretches the whole CD-ROM to be in a maximum state through a shift sheet, and then the optical disk can be completely covered; and after the portable and stretchable CD-ROM is connected with a computer through a USB cable, the CD-ROM can be used like a common CD-ROM for read-write operation. When the user needs to take out the optical disk, the user just needs to press the switch, and then a system rapidly stops rotation of the optical disk; and the user contracts the CD-ROM to be in a minimum state through the shift sheet, and then the optical disk can be taken down easily.

Description

technical field [0001] The invention relates to a portable retractable optical drive. Background technique [0002] With the development of ultra-thin portable notebooks, more and more OEM manufacturers have begun to abandon the installation of optical drives in their notebook products. For example, Apple has completely abandoned optical drives in the product lines of Macbook Pro, Macbook Air and iMac. This is mainly due to the mechanical structure of the optical drive. Generally, optical drives have the disadvantages of easy damage, high power consumption, and large volume. [0003] Although more and more notebooks or desktops have canceled the installation of optical drives, users still need to use optical drives in many cases, such as operating system installation, file backup, listening to music with CD discs, and so on. For this reason, many computer peripheral manufacturers have released corresponding external optical drives to meet the needs of users. ...
