    摘要: A recording medium records data including a digital stream where video information has been encoded. A recording region of the recording medium has a first recording region where reading is performed at a first read rate, and a second recording region where reading is performed at a second read rate that is faster than the first read rate. The data is classified into digital stream data having a real-time attribute and a data file having a non-real-time attribute in a file system of the data. The digital stream is not continuously recorded spanning a boundary between the first recording region and the second recording region. The data file is permitted to be continuously recorded spanning the boundary.

    摘要: Systems and methods are disclosed for binding shingled recording bands in data storage devices, particularly devices employing shingled magnetic recording. In one embodiment, an apparatus may comprise a controller configured to define boundaries of an area of a data storage medium based on a constraint and a list of defective sectors. In another embodiment, an apparatus may comprise a data storage device including a memory configured to store data in a shingled manner where one track partially overlaps an adjacent track, and a controller configured to define boundaries of a plurality of bands, each band including a plurality of tracks of the memory, based on the results of an error discovery scan for defective sectors of the memory.

    摘要: According to one embodiment, a controller in a magnetic disk drive manages the influence, on a first track on a disk, of data writes to tracks within outer and inner adjacent track ranges, using first and second counters associated with the first track. The first and second counters are indicative of the numbers of data writes to tracks within the outer and inner adjacent track ranges, respectively. Based on the values of the first and second counters, the controller reads data from the first track, and rewrites the read data to the first track.

    摘要: A shingled magnetic recording (SMR) hard disk drive (HDD) essentially eliminates the effect of far track erasure (FTE) in the boundary regions of annular data bands caused by writing in the boundary regions of adjacent annular data bands. The extent of the FTE effect is determined for each track within a range of tracks of the track being written. Based on the relative FTE effect for all the tracks in the range, a count increment (CI) table or a cumulative count increment (CCI) table is maintained for all the tracks in the range. For every writing to a track in a boundary region, a count for each track in an adjacent boundary region, or a cumulative count for the adjacent boundary region, is increased. When the count reaches a predetermined threshold the data is read from that band and rewritten to the same band.
