Abstract
An exemplary magnetic head structure and method of manufacture is described. In one example, the method includes forming a support surface having a longitudinal width associated with at least one data transducer and a reduced longitudinal width region offset along a lateral direction from the at least one data transducer. The method further includes lapping the support surface such that the at least one data transducer is raised or elevated relative to at least a portion of the support surface. In one example, the at least one data transducer is raised relative to laterally offset portions of the support surface, and in one example, to laterally offset portions positioned between adjacent data transducers.
Claims26
A magnetic head structure for use with magnetic storage media, the structure comprising:
- a support surface having a width along a longitudinal direction and a length along a lateral direction, the support surface for supporting the media as the media moves along the longitudinal direction;
- and
- at least one data transducer disposed with the support surface, wherein the support surface has a longitudinal width associated with the at least one data transducer and a reduced longitudinal width region offset along the lateral direction from the at least one data transducer.
A tape drive system including a magnetic head assembly for writing to and reading from magnetic recording media, comprising:
- an actuator for positioning a magnetic head assembly adjacent a tape path, the magnetic head assembly including,
- a support surface having a width along a longitudinal direction and a length along a lateral direction, the support surface for supporting the media as the media moves along the longitudinal direction;
- and
- at least one data transducer disposed with the support surface, wherein the support surface has a longitudinal width associated with the at least one data transducer and a reduced longitudinal width region offset along the lateral direction from the at least one data transducer.
A method for manufacturing a head structure for use with storage media as it passes thereby along a longitudinal direction, the method comprising:
- forming a support surface having a longitudinal width associated with at least one data transducer and a reduced longitudinal width region offset along a lateral direction from the at least one data transducer;
- and
- lapping the support surface such that the at least one data transducer is raised relative to at least a portion of the support surface.
