Abstract
A magnetic head according to an embodiment of the present technology includes: a recording surface that has a first region corresponding to a position where a magnetic gap is provided in a length direction, and a second region corresponding to a position where the magnetic gap is not provided in the length direction, a plurality of groove portions crossing from one end in a width direction orthogonal to the length direction to the other end in the width direction being provided in the second region, and records a signal on a magnetic tape with the magnetic gap.
Claims15
A magnetic head, comprising:
- a recording surface that has a first region corresponding to a position where a magnetic gap is provided in a length direction and a second region corresponding to a position where the magnetic gap is not provided in the length direction, a plurality of groove portions crossing from one end in a width direction orthogonal to the length direction to the other end in the width direction being provided in the second region, and records a signal on a magnetic tape with the magnetic gap.
A servo pattern recording apparatus, comprising:
- a servo write head having a recording surface that has a first region corresponding to a position where a magnetic gap is provided in a length direction and a second region corresponding to a position where the magnetic gap is not provided in the length direction, a plurality of groove portions crossing from one end in a width direction orthogonal to the length direction to the other end in the width direction being provided in the second region, and records a servo pattern on a magnetic tape with the magnetic gap.
A tape drive device, comprising:
- a magnetic head having a head surface that has a first region corresponding to a position where a magnetic gap is provided in a length direction and a second region corresponding to a position where the magnetic gap is not provided in the length direction, a plurality of groove portions crossing from one end in a width direction orthogonal to the length direction to the other end in the width direction being provided in the second region, and records a data signal on a magnetic tape with the magnetic gap.
A method of producing a magnetic tape, comprising:
- causing, on a recording surface of a servo write head that has a first region corresponding to a position where a magnetic gap is provided in a length direction and a second region corresponding to a position where the magnetic gap is not provided in the length direction, a plurality of groove portions crossing from one end in a width direction orthogonal to the length direction to the other end in the width direction being provided in the second region, a magnetic tape to travel in the width direction;
- and
- recording a servo pattern on the magnetic tape with the magnetic gap while causing the magnetic tape to be in contact with the first region and at least part of the magnetic tape to float from the second region.
A recording method, comprising:
- causing, on a recording surface of a magnetic head that has a first region corresponding to a position where a magnetic gap is provided in a length direction and a second region corresponding to a position where the magnetic gap is not provided in the length direction, a plurality of groove portions crossing from one end in a width direction orthogonal to the length direction to the other end in the width direction being provided in the second region, a magnetic tape to travel in the width direction;
- and
- recording a data signal on the magnetic tape with the magnetic gap while causing the magnetic tape to be in contact with the first region and at least part of the magnetic tape to float from the second region.
