ABSTRACT:
A method and apparatus for providing low cost multi-channel magnetic tape recording is disclosed. A tape head having the same number of read and write cores as a typical low cost single channel recording head, is modified to achieve multi-channel recording. One channel performs conventional read-after-write while the other channel performs "virtual" read-after-write, that is, the track in the second channel is read only after that track has been written over the entire length of the tape. As the direction of tape travel changes, the channel performing read-after-write alternates.
