Claims

[Scope of utility model registration request]

A magnetic tape erasing bag 7 moves the magnetic tape close to the magnetic head to erase information that has already been recorded on the magnetic tape. an erase signal generator that generates an erase current, an erase circuit that generates a current for erasing, an erase head that applies an erase current to the magnetic tape to erase information on the magnetic tape, and detects the end of the magnetic tape. What is claimed is: 1. A magnetic tape erasing device, comprising: a termination detector for erasing a magnetic tape.
