Description

Compact disk case

The present invention relates to a compact disk case for accommodating a compact disk (CD) in which a program or music is stored therein to be protected from an external shock or to be easy to use.

In general, a compact disc is an abbreviation of Compact Disk, which regularly drills small grooves called pits along a track pitch of 1.6 micrometers, so that digital information (signal 1 and 0) ) Is a 12cm diameter disc that records 1 and 0 signals by reflecting the laser beam on the recording pattern (pit) and changing the reflected light. This means that in the analog recording method, the signal level is recorded on the disc. In contrast to linearly corresponding to the depth of the (sound groove) and the automatic density of the magnetic tape, the digital recording method determines whether a signal (reflected light of laser beam) is present, that is, 1 or 0.

In addition, the surface of the compact disc has an aluminum thin film layer with high reflectance and the incident laser light is reflected back mostly in the part without the pit, but in the part with the pit, the light is refracted in the pit, that is, a small hole, and a part of the reflected light It does not come back to an objective lens outside. Therefore, by detecting the presence or absence of reflected light, 1 and 0, which are recording information, can be discriminated. In contrast to records, compact discs record data clockwise from the inside out.

Such a compact disc (CD) can be stored therein to install a program in a computer through a CD-ROM, or to store music and play music through the CD-ROM or audio.
