The magnetic head comprises a recording module in which a plurality of recording elements are provided, and a reproducing module in which a plurality of reproducing elements are provided. The recording module and the reproducing module are disposed along a longitudinal direction of the magnetic tape. A pair of first servo reading elements of the recording module and a pair of second servo reading elements of the reproducing module are shifted from each other by a predetermined difference along one direction in the width direction of the magnetic tape. The predetermined difference is defined based on a pitch between a plurality of tracks formed using an SMR method and a length of the recording element in the width direction of the magnetic tape.

This magnetic tape drive is used in a magnetic tape cartridge which is equipped with a magnetic tape and a storage medium. The storage medium stores geometric characteristic information. The magnetic tape records geometric characteristic information. The processor of the magnetic tape drive leaves second geometric characteristic information on the storage medium by deleting the first geometric characteristic information from the storage medium. The second geometric characteristic information is information for which it is possible to identify the recording position at which the geometric characteristic information is recorded on the magnetic tape. The first geometric characteristic information is information other than the second geometric characteristic information.

Controlling a shingled magnetic recording (SMR) hard drive involves attempting a sequential write to a first sector of a sequence of sectors and, responsive to encountering a write inhibit boundary corresponding to the first sector, continuing the write to the next available sector in the sequence of sectors for the write. Thus, instead of that write inhibit triggering a hard error, the data is adaptively written to the next down-track physical sector possible, i.e., “sliding” to the next sector. This does not require an additional disk revolution thus there is negligible performance penalty. The write may be continued to the next track if necessary, and may continue through the entire zone, to maintain all the data in sequential form for performance and large block protection purposes.

In response to loading of the tape cartridge into the tape drive, the HRTD is received from the off-tape non-volatile memory.

Controlling a shingled magnetic recording (SMR) hard drive involves writing, to a first track of a zone pre-sized based on a nominal track width based on an expected mean track width across an entire zone, a portion of a write operation according to the nominal track width. Then, based on the positional accuracy of the first track writing, determining a second track position for an adjacent second track, and writing the second track another portion of the write operation according to the determined second track position. Thus, the determination and position of a given track is determined by the positional accuracy of a previously written track, considering for example the position error signal corresponding to the writing of the previously written track. Thus, the track pitch is effectively defined by the average positional error across a zone rather than by a worst-case scenario positional error across the zone.

Disclosed are storage devices and methods relating to reading staggered bits recording patterns in which the data bits on adjacent tracks recorded on magnetic media are staggered in such a way that a single reader detects a combined signal from data bits on multiple tracks at selected signal sampling locations. A signal shaping algorithm is used to deconvolve the combine signals, thus isolating each of the tracks from one another so that single track bit sequences can be decoded. In this way, staggered bits patterns can use intertrack interference effects for advantage, allowing readers to read multiple bit tracks simultaneously and without ambiguity.
