A write command is received to write data in a Conventional Magnetic Recording (CMR) realm of a disk to be formatted for writing data in non-overlapping tracks. The disk includes a plurality of areas of the disk that can be formatted as a CMR realm or as a Shingled Magnetic Recording (SMR) realm formatted for writing data in overlapping tracks. It is determined whether performance of the write command would require writing to begin in a portion of the CMR realm that has not been written with non-overlapping tracks. In response to determining that the performance of the write command would require writing to begin in a portion of the CMR realm that has not been written with non-overlapping tracks, a predefined data pattern is written using non-overlapping tracks in the portion of the CMR realm that has not been written with non-overlapping tracks.

A data storage device comprises a host interface and a storage control system coupled to the host interface. The storage control system is configured to perform a write process to write data to storage in response to one or more write operations received over the host interface from a host, determine a quality of written data produced by the write process; and in response to when the quality of the written data fails to satisfy one or more quality criteria, obtain data parity information to compensate for the quality of the written data and write the data parity information to storage.

The magnetic tape includes a non-magnetic support; and a magnetic layer including ferromagnetic powder and a binding agent on the non-magnetic support, in which the magnetic layer includes a timing-based servo pattern, the ferromagnetic powder is ferromagnetic hexagonal ferrite powder having an activation volume equal to or smaller than 1,600 nm.sup.3, an XRD intensity ratio Int(110)/Int(114) obtained by an X-ray diffraction analysis of the magnetic layer by using an In-Plane method is 0.5 to 4.0, a vertical direction squareness ratio of the magnetic tape is 0.65 to 1.00, and an edge shape of the timing-based servo pattern specified by magnetic force microscope observation is a shape in which a difference (L.sub.99.9L.sub.0.1) is equal to or smaller than 180 nm, and a magnetic tape device including the magnetic tape.

A data storage device is disclosed comprising a head actuated over a disk comprising a plurality of tracks. A plurality of interlaced recording (IR) zones are defined on the disk, wherein each IR zone comprises a plurality of top tracks partially overlapping a plurality of bottom tracks. First data is written to the bottom tracks of a first IR zone, and the first IR zone is identified as a cold IR zone that is storing cold data. In response to identifying the first IR zone as a cold IR zone, second data is written to the top tracks of the first IR zone.

A method of manufacturing magnetic tape storage data cartridges may include cutting a master tape having a first width into multiple tape sections that each have a smaller width than the first width, cleaning the tape sections to remove debris caused by the cutting, and writing the servo tracks on each tape section after the tape section is cleaned. The method may further include spooling each tape section into a respective tape cartridge after writing the servo track on the tape section.

The present technology relates to a signal processing apparatus, a signal processing method, and a program by which, in reproducing transmitted encoded data in real time, buffer overflow can be prevented from occurring on a reception apparatus side even if it is transmitted with a compression rate of the encoded data being varied in a manner that depends on communication condition. Encoded data including transmitted audio data is buffered by a reception buffer. At this time, the quantity of encoded data buffered by the reception buffer is managed in units of processing according to an encoding method. The present technology is applicable to a real-time content reproduction system utilizing a communication system.
