Abstract
A magnetic tape recording system employing a single bump read-while-write head, methods of minimizing crossfeed signals between the read and write channels of magnetic tape recording systems, and electronic circuitry to implement such methods.
Claims13
A magnetic recording head, comprising:
- a) a substrate,
- b) a film stack on the substrate, and
- c) an encasing material surrounding the film stack;
- the film stack comprising a plurality of pole materials and at least one magnetoresistive (MR) element, arranged within the film stack to define a single bump contour comprising at least one read-while-write (RWW) channel;
- each RWW channel comprising at least one write gap, at least one MR read gap, and a total of at least three total read and write gaps per RWW channel.
