Optical Storage Mediums

Optical Storage Mediums Optical Storage Mediums James Ng The most common route of storing data in a computer is magnetic. We have hard contains and floppy disks (soon making way to the CD-ROM), both of which usher out store some amount of data. In a disk drive, a read/write promontory (usually a coil of wire) passes over a spinning disk, generating an electrical current, which defines a bit as either a 1 or a 0. There are limitations to this though, and that is that we mickle and make the head so small, and the tracks and sectors so close, before the drive starts to suffer from interference from nearby tracks and sectors.

What other option do we have to store massive amount of data? We can put on light. Light has its advantages. It is of a short wavelength, so we can place tracks very close together, and the size of the track we use is dependent only on one thing - the glossiness of the light we use. An optical medium typically involves some tell apart of laser, for laser light does not diver...If you want to get a full essay, order it on our website: Orderessay
