Abstract
A magnetic head including a plurality of head element units provided along a width direction with respect to a magnetic tape. Each head element unit is provided with at least one recording element for recording a data signal on the magnetic tape and at least one reproducing element for reproducing a data signal from the magnetic tape. In each head element unit, an AC erase head for performing AC erase on a data track of the magnetic tape is positioned upstream in a tape travel direction with respect to the recording element.
Claims12
A magnet tape drive comprising:
- a tape travel unit to be used for a magnetic tape travel;
- a magnetic head;
- and
- an AC erase current generator which supplies an AC erase current, for performing an AC erase on a data track of a magnetic tape, to respective AC erase elements provided on the magnetic head, wherein
- the magnetic head includes a plurality of head element units which are provided along a width direction with respect to the magnetic tape, wherein
- each head element unit is provided with at least one recording element for recording a data signal on the magnetic tape and at least one reproducing element for reproducing a data signal from the magnetic tape, and wherein
- the AC erase element is positioned upstream in a tape travel direction with respect to the recording element,
- said tape drive further comprising means (7) for generating the AC erase current to produce a magnetic field having a frequency that is higher than the frequency of the data signal, produced by the recording current, which is supplied to the recording element.

A magnetic tape drive comprising:
- a tape travel unit to be used for a magnetic tape travel;
- a magnetic head including a plurality of head element units arranged along a width direction with respect to a magnetic tape, each of the head element units comprising:
- at least one recording element for recording a data signal on the magnetic tape,
- at least one reproducing element for reproducing the data signal from the magnetic tape,
- the recording element and the reproducing element being arranged adjacent to each other, and
- an AC erase element for AC erasing one or more data tracks on the magnetic tape, the AC erase element being positioned upstream from the recording and reproducing elements in a tape travel direction of the magnetic tape;
- and
- an AC erase current generator which supplies to each AC erase element an AC erase current for performing an AC erase on the data tracks of the magnetic tape, and for producing an AC magnetic field having a higher frequency than that produced by a recording current supplied to the recording element.
