A storage control apparatus controls a tape apparatus including a plurality of tape drives. The storage control apparatus is configured to calculate, when causing the tape apparatus to execute write processing of dividing write data into a predetermined size and writing to a plurality of magnetic tapes, a write start position of the write data for each of the plurality of magnetic tapes where the write start position being different in each of the plurality of magnetic tapes and instruct the tape apparatus with the write start positions, and specify, when a reading range is designated, a read start position indicating a head of data in the reading range for each magnetic tape, and instruct the tape apparatus to read data in the reading range in an order from a magnetic tape of which the read start position is closer to an end of the magnetic tape.

A multimedia signal processing system utilizes an easily manipulated, low-cost storage and display system that allows the user to view a television program and instantly review previous scenes within the program. The invention also allows the user to store selected programs while simultaneously watching or reviewing another. A versatile system architecture enables providing the invention in multiple configurations, each adapted to receive input signals from a different source. At the highest level, the system includes an input section and an output section. Across all configurations, the output section remains substantially the same, while the input section varies according to the signal type and the source. Thus, several configurations are provided, each one requiring only minor system board modifications. The system architecture thus simplifies the design and manufacturing challenge presented by producing units to serve different markets, such as digital satellite, digital cable and analog cable.

An automatic playback overshoot correction system predicts the position in the program material where the user expects to be when the user stops the fast forward progression of the program material. The system determines the position where the program material was stopped and transitions to the new mode that the user selected, starting at the stopped position with an overshoot correction factor subtracted from it. The system uses a prediction method to correctly place the user within the program upon transition out of fast forward mode and determines if the speed of the fast forward mode and then automatically subtracts a time multiple to the frame where the transition was detected and positions the user at the correct frame. The time multiple is fine tuned if the user is consistently correcting after the fast forward mode stops.

An approach for improving the writing an index file on tape storage by switching, via a tape drive, write sequences in an index partition, in which the tape drive switches between a normal wrap sequence and a reverse wrap sequence. Further, embodiments write the index information by the normal wrap sequence during initialization of the tape media, in which the tape media is being mounted for the first time. Additionally, embodiments write the index information by the reverse wrap sequence during an unmounting the tape media for the first time, and wherein the tape media is mounted based on index information written at a rearmost end of one or more data partitions during second and subsequent mounting.

Aspects of the present disclosure relate to a method of writing a dataset to a tape, the dataset comprising a plurality of sub datasets, each sub dataset including a plurality of headers and a plurality of records. The method includes storing, in each header of each sub dataset, at least a portion of a record range indicator indicating a range of records included in the dataset.

A recording device including at least one processor, wherein the processor is configured to: acquire, for attached information attached to each of a plurality of recording target data recorded on a recording medium, a first relevance degree according to a frequency at which data other than the recording target data attached with information having the same contents as the attached information is read out within a period determined in advance; derive, for each combination of a plurality of recording target data, a second relevance degree representing a possibility that the plurality of recording target data included in the combination is read out within the period based on the first relevance degree; and classify the plurality of recording target data into groups based on the second relevance degree and perform control of recording the classified data on the recording medium for each group.

A data storage device is disclosed comprising at least one head configured to access a magnetic tape. The head is used to write contiguously to the magnetic tape a first preamble, followed by a first sync mark, followed by symbols of a first data sector, followed by a second sync mark, followed by a second preamble, followed by a third sync mark, followed by symbols of a second data sector.

A recording device including at least one processor, wherein the processor is configured to: derives a number to be grouped in a case where plural data are collectively recorded on a recording medium based on condition information including a size of the plurality of data to be recorded on the recording medium, a size of metadata related to each of the plurality of data, and an assumed value of a number of the data read out from the recording medium within a period determined in advance; and performs control to collectively record the data on the recording medium for each of the number to be grouped.

Systems and techniques for modifying a subsection of uploaded media are presented. An instruction component receives a media file and a media enhancement instruction that includes enhancement data and media interval data for a first segment of the media file. A processing component modifies the first segment of the media file associated with the media interval data based on the enhancement data to generate an edited first segment of the media file. A finalization component generates an edited version of the media file that includes the edited first segment of the media file and at least a second segment of the media file that is not modified based on the enhancement data.
