Abstract
A method and a system for recording and reading magnetic information on a linear tape are disclosed. A write head is disclosed that is wider than the read head. Tracks of discrete, elongate bits of information, which are oriented perpendicular to the long axis of the tape, are recorded by the write head. The read head avoids crosstalk without employing azimuth recording techniques by re-positioning the read head over the center of the narrowed track prior to beginning the reading process. The combination of the narrow read head and re-positioning of the read head enables track trimming, which provides high lateral track density. The drive disclosed is capable of reading and recording on existing QIC tapes, as well as higher density cartridges.
