The TU60 DECasette Tape Transport magnetic tape drive was intended to replace paper tapes. The media is physically identical to the one used with audio cassettes, with tape 0.15" wide, but it uses a different metal-oxide coating.
A cassette can hold at least 93KB; data on the cassette is protected by a CRC. A TU60 unit contained two drives, each with associated control electronics; both could move at the same time, but only one can read or write at a time.
