Explanation

CD R/DVD R, CD ROM/DVD ROM, CD RW/DVD RW and magnetic tapes are common backing storage media.

  • CD R/DVD R: Applications which require a single ‘burning’ of data, e. g. CDs - recording of music downloads from the Internet, recording of music from MP3format, recording of data for archiving or backup purposes.

  • DVDs – recording of film movies and television programs.

  • CD ROM/DVD ROM: Applications which require the prevention of deletion of data, accidental or otherwise. CDs used by software companies for distributing software programs and data; by Music companies for distributing music albums and by book publishers for distributing encyclopedias, reference books etc. DVDs used by film distributors.

  • CD RW/DVD RW: Applications which require the updating of information and ability to record over old data. Not suitable for music recording but is very useful for keeping generations of files. DVDs have between five and ten times the capacity of CDs.

  • Magnetic tapes: Any application which requires extremely large storage capacity where speed of access is not an issue. Uses serial access for reading and writing. Used for backups of file servers for computer networks. Used in a variety of batch processing applications such as reading of bank cheques, payroll processing and general stock control.
