  • Optical devices operate using a laser beam. The laser reads from and writes to the disk. This disk is made up of polycarbonate plastic coated with a thin layer of reflective material. The reflective material is then etched into by the laser; this causes microscopic pits to form on the surface.
  • Solid state backing storage is a silicon chip which consists of a grid of columns and rows of cells. Each cell comprises of 2 transistors separated by a thin oxide layer. They have no moving parts

    6. 6. Optical backing storage media: Advantages Disadvantages DVD has a greater capacity then a Data transfer rates are slower than a hard CD disks’ CDs are cheaper to buy Data access times are longer than a hard disks Both hold more data than a floppy disk. Both are cheaper and more Back to Backing robust than hard disks Storage and Media Devices
    7. 7. Optical backing storage media: Advantages Disadvantages Cheaper than CD/DVD Can only be recorded on RW s once. Once they are used; Not all CD players there is no chance that recognize CD R s by accident something will rewrite over it. Back to Backing Storage and Media Devices
