The present technology relates to a recording apparatus, a recording method, and a program capable of avoiding a buffer overflow at the time of reproduction.

Each packet is separated from a packet string, and information indicating an arrival timing of each packet is output. The packet is divided into divided packets having a size which does not cause a buffer overflow, and a packet arrival time of each divided packet is embedded in a header of the divided packet. The present technology is applied to the recording apparatus.

An information recording medium (10) including a first region (11) in which medium identification information has been recorded, a data region (13), and a second region (12) which is positioned between the first region (11) and the data region (13) and in which control information has been recorded, in which an area of the first region (11) is greater than an area of the second region (12) in size.

Technologies are provided for using an index in one region of a storage device to track modifications to data stored in another region of the storage device. The index can be stored in a first storage region using a first storage format, and data items can be stored in a second storage region using a second storage format. The index can map logical identifiers for data items to locations in the second storage region where the data items are stored. Instead of modifying a data item in the second storage device region, an entry in the index can be updated to mark the data item as deleted. Requests for data items can be reconciled using the index before returning the requested data items. Storage locations in the second region that are associated with index entries that are marked as deleted can be reclaimed and used to store additional data items.

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.

A data recording apparatus including: a data reading device configured to read data from a first recording medium and configured to store data and first management data for managing the data by file; a data recording device configured to record data on a second recording medium; a management data producing device configured to produce second management data for managing data recorded on the second recording medium based on the first management data of the first recording medium on which the data recorded on the second recording medium has been recorded; a data determining device configured to determine data unrecorded on the second recording medium by comparing the first management data read by the data reading device from the first recording medium with the second management data recorded on the second recording medium; a control device configured to read the data determined by the data determining device from the first recording medium and cause the recording device to record the read data onto the second recording medium; and a display device configured to display the recording status of data, managed by the first management data read by the reading device from the first recording medium, on the second recording medium, wherein the recording status includes one of recording of data complete, recording of data in progress, and recording of data yet to begin.

The present disclosure describes systems and techniques relating to storage devices, such as storage devices that employ Shingled Magnetic Recording (SMR). According to an aspect of the described systems and techniques, a device includes: circuitry configured to write stored data and parity data to discrete portions of a Shingled Magnetic Recording (SMR) track in a SMR storage device; and circuitry configured to recover stored data for one of the discrete portions of the SMR track using the parity data and the stored data read from remaining ones of the discrete portions of the SMR track.

In response to a rotation of timing-based servo (TBS) patterns of a first servo band and a second servo band, heights of top and bottom portions of servo stripes of servo frames of the TBS patterns are adjusted to compensate for changes in a usable height of the servo stripes caused by the rotation.

Mechanisms are provided, in a storage system controller of a storage system, for writing data to a storage medium. The storage system controller receives a write request to write a block of data to the storage medium. The write request does not specify a location on the storage medium to which to write the block of data. The storage system controller determines a current position of a write mechanism of the storage system relative to the storage medium and determines a location on the storage medium to write the block of data based on the current position of the write mechanism. The storage system controller sends a notification to a host system identifying the location of the block of data on the storage medium as determined by the storage system controller. The writing mechanism writes the block of data to the determined location on the storage medium.

A tape drive-implemented method, according to one embodiment, includes: causing a servo reader to move laterally in a first direction over a high-density servo pattern on a moving magnetic tape, receiving a readback signal from the servo reader as the servo reader moves laterally in the first direction, using amplitudes of the readback signal to determine a maximum energy value of each of the at least two periodic waveforms, and using the maximum energy values to set a gain parameter for each of the respective periodic waveforms. The first direction is perpendicular to a longitudinal axis of the magnetic tape. Moreover, the high-density servo pattern includes a plurality of high-density servo tracks, the servo tracks including at least two patterns written at different frequencies to produce different periodic waveforms during readback. Other systems, methods, and computer program products are described in additional embodiments.
