Claims

[Claims for Utility Model Registration] A device comprising a magnetoresistive element, which follows a write head that records data on a magnetic tape during a recording operation and reads data recorded by the write head;
A monitor read head for checking whether or not the data is being recorded correctly; a playback read head comprising a magneto-resistance element for reading data recorded on the magnetic tape during a playback operation; and a playback read head for enabling the playback read head to operate. a reproduction current supply circuit that supplies a current; a monitor current supply circuit that supplies a current that enables the monitor reading head; and a reproduction current supply circuit that sets the reproduction current supply circuit to an operating state during a reproduction operation and sets the reproduction current supply circuit to an operating state during a recording operation. A tape recorder comprising a head switching control circuit that sets a monitor current supply circuit to an operating state.
