Abstract
Described are magnetic recording heads that include a read transducer and a write transducer, with the two transducers being arranged in a side-by-side configuration.
Claims20
A recording head comprising:
- a bottom surface adapted to be oriented to face a magnetic recording medium surface during use, the bottom surface having:
- a down-track dimension between a leading end and a trailing end, and
- a cross-track dimension perpendicular to the down-track dimension,
- only one write transducer located at a location of the down-track dimension and the cross-track dimension, and
- a read transducer located at a location of the cross-track direction that is spaced a distance of at least 10 microns from the location of the write transducer in the cross-track dimension.
