Abstract
In one general embodiment, an apparatus includes a magnetic head. The magnetic head has a first portion and a second portion, the first portion and the second portion together providing a tape bearing surface. The first portion has two pieces flanking the second portion in an intended direction of tape travel thereacross. The second portion has at least one array of transducers. A longitudinal axis of each of the at least one array is defined between opposite ends thereof. The longitudinal axis of each of the at least one array of transducers is oriented at an angle relative to the line oriented orthogonally to the intended direction of tape travel thereacross, the angle being between 0.2° and about 10°.
Claims17
An apparatus, comprising:
- a magnetic head, the magnetic head having:
- a first portion and a second portion, the first portion and the second portion together providing a tape bearing surface,
- wherein the first portion has two separate pieces flanking the second portion in an intended direction of tape travel thereacross, the two separate pieces of the first portion being spaced from the first portion in the intended direction of tape travel thereacross,
- the second portion having at least one array of transducers,
- wherein a longitudinal axis of each of the at least one array is defined between opposite ends thereof,
- wherein the longitudinal axis of each of the at least one array of transducers is oriented at an angle relative to a line oriented orthogonally to an intended direction of tape travel, the angle being between 0.2° and about 10°;
- and
- a mechanism coupled to the magnetic head for orienting the second portion to control a transducer pitch presented to a tape by rotating the second portion about an axis oriented orthogonal to a plane tangent to the tape bearing surface of the second portion.
An apparatus, comprising:
- a magnetic head, the magnetic head having:
- a first portion and a second portion, the first portion and the second portion together providing a tape bearing surface,
- wherein the first portion has two separate pieces flanking the second portion in an intended direction of tape travel thereacross,
- wherein the inner edges of the first portion that directly oppose outer edges of the second portion are straight along an entire length thereof,
- the two separate pieces of the first portion being spaced from the first portion in the intended direction of tape travel thereacross whereby air gaps are defined between outer edges of the second portion and the inner edges of the first portion,
- the second portion having at least one array of transducers,
- wherein a longitudinal axis of each of the at least one array is defined between opposite ends thereof,
- wherein the longitudinal axis of each of the at least one array of transducers is oriented at an angle relative to a line oriented orthogonally to an intended direction of tape travel, the angle being between 0.2° and about 10°;
- and
- a mechanism coupled to the magnetic head for orienting the second portion to control a transducer pitch presented to a tape by rotating the second portion about an axis oriented orthogonal to a plane tangent to the tape bearing surface of the second portion.
