What type of magnetic tape is used to record computer  programs and data, and what are the additional thickness and  quality standards for this type of tape?
by

1 Answer

Answer :

digital magnetic tape is for computer programs and data. Its  base material is about 50% thicker. The tape’s surface must not have  blemishes or coating flaws because losing even one digital data bit  could ruin the recorded computer program or data.
