Narrow-tracking magnetic recording head

A higher track density would increase the capacity of magnetic recording systems and could reduce the time required for access to the contents. Higher track densities can be achieved by registering accurately narrow recorded tracks spaced closely together. A magnetic head capable of recording information at high linear densities within extremely narrow tracks has been developed. Narrow tracks are achieved by offsetting the magnetic pole pieces of the head so that only the narrow overlapping portions form the effective writing and reading section. The head performance is determined analytically and experimentally.
