Abstract
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.
Claims22
A data storage device configured to access a magnetic tape, the data storage device comprising:
- at least one head configured to access the magnetic tape;
- and
- control circuitry configured to use the head 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 data storage device configured to access a magnetic tape, the data storage device comprising:
- at least one head configured to access the magnetic tape;
- and
- control circuitry configured to:
- use the head to continuously write a plurality of data sectors to the magnetic tape without leaving a gap between each data sector;
- and
- use the head 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 data storage device comprising:
- a magnetic tape;
- at least one head configured to access the magnetic tape;
- and
- a means for using the head to continuously write a plurality of data sectors to the magnetic tape without leaving a gap between each data sector, wherein the means for using the head to continuously write comprises a means for contiguously writing 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.
