Sector sliding in shingled magnetic recording hard disk drive

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.

Single track isolation in staggered bits magnetic recording

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.

Multi-revolution hard disk drives with reduced servo overhead

Disclosed are hard disk drives (HDDs), and methods for use therewith, that utilize reduced overhead servo fields, thereby simplifying the servo system. Reduced overhead servo fields may be of particular use in HDDs that utilize multi-revolution storage techniques to store data at much higher densities than what is possible for conventional HDDs. The relaxed performance requirements of high-density, multi-revolution drives provides opportunities for reducing servo overhead, thereby potentially further increasing the areal density capability of the magnetic media. Servo overhead may also be reduced by placing certain servo data on flash or other memory off of the media disk rather than in the servo fields written to the media disk.
