Abstract
An apparatus and method for writing data to be played back onto a tape is provided. Included is an acquisition unit for acquiring data to be written onto the tape, a writing unit for writing the data to the tape, and a determination unit for determining a data amount of a leading part of the data to be stored in a place separate from a place where the data is stored so that a part following the leading part is made ready to be played back before playback of the leading part ends, to reduce the time taken to read the data from the tape. Also included is an extraction unit for extracting the data and a storage unit for storing the leading part of the data.
Claims14
An apparatus for writing data onto a tape comprising:
- an acquisition unit for acquiring data;
- a writing unit for writing the data onto the tape;
- a determination unit for reducing a time taken to read the data from the tape, the determination unit determining a data amount of a leading part of the data to be stored in a first place separate from a second place where the data is stored so that a portion of the data following the leading part of the data is ready to be played back before playback of the leading part of the data ends;
- an extraction unit for extracting the leading part of the data;
- and
- a storage unit for storing the leading part extracted by the extraction unit.
An apparatus for writing data onto a tape comprising:
- an acquisition unit for acquiring data to be written onto the tape;
- an extraction unit for extracting a first part of the data and a second part of the data, following the first part of the data;
- a determination unit for determining a distance between a position at which the first part of the data is written on the tape and a position at which the second part of the data is written on the tape, so that the second part of the data is ready to be played back before playback of the first part of the data ends;
- and
- a writing unit for writing the first part of the data at a predetermined position on the tape and the second part of the data at a position located away from the predetermined position by the distance determined by the determination unit.
A method for writing data onto a tape comprising the steps of:
- acquiring data to be written onto the tape;
- writing the data onto the tape;
- determining a data amount of a leading part of the data to be stored in a place separate from a place where the data is stored so that a part of the data following the leading part of the data is ready to be played back before playback of the leading part ends for reducing a time taken to read the data from the tape;
- extracting the leading part of the data having the determined data amount from the acquired data;
- and
- a storage unit for storing the extracted leading part of the data.
A method for writing data onto a tape the method comprising the steps of:
- acquiring data to be written onto the tape;
- determining a distance between a position at which a first part of the acquired data is written on the tape and a position at which a second part of the data following the first part is written on the tape, so that the second part is made ready to be played back before playback of the first part ends;
- and
- writing the first part of the data at a predetermined position on the tape and the second part of the data at a position located a determined distance from the predetermined position.
A program product for causing a computer to serve as an apparatus for writing data onto a tape, the data to be played back, the program product causing the computer to serve as:
- an acquisition unit for acquiring a plurality of pieces of data to be written onto the tape;
- and
- a writing unit for writing respective first parts of the pieces of data acquired by the acquisition unit in a first area on the tape and respective second parts of the pieces of data following the first parts in a second area on the tape so that the second parts are made ready to be played back before playback of the first parts ends.
