Abstract
Provided is a recording medium onto which a plurality of tracks that constitute a unit as one unit of signal processing for reproducing data are recorded, each of the plurality of tracks being recorded with at least data and, as a preamble necessary for controlling the reproduction of the data, a separation pattern necessary for detecting a positional relationship between a reproducing head and the plurality of tracks in a track width direction and synchronization patterns for synchronization processing, the synchronization patterns being recorded in front and rear of the separation pattern in a running direction of the plurality of tracks.

A recording medium onto which a plurality of tracks that constitute a unit as one unit of signal processing for reproducing data are recorded, each of the plurality of tracks being recorded with at least data and, as a preamble necessary for controlling the reproduction of the data, a separation pattern necessary for detecting a positional relationship between a reproducing head and the plurality of tracks in a track width direction and synchronization patterns for synchronization processing, the synchronization patterns being recorded in front and rear of the separation pattern in a running direction of the plurality of tracks.
A recording apparatus recording, onto a recording medium using a recording head, a plurality of tracks that constitute a unit as one unit of signal processing for reproducing data, comprising:
- a recording encoding section to encode data to be recorded for each of the plurality of tracks;
- a preamble adding section to add, to the data of each of the plurality of tracks that has been encoded by the recording encoding section, as a preamble necessary for controlling the reproduction of the data, a separation pattern necessary for detecting a positional relationship between a reproducing head and the plurality of tracks in a track width direction, the separation pattern being provided with synchronization patterns for synchronization processing in front and rear thereof;
- and
- a multitrack recording section to carry out processing for recording the data of each of the plurality of tracks, to which the preamble has been added, onto the recording medium using the recording head.
A reproducing apparatus reproducing a recording medium onto which a plurality of tracks that constitute a unit as one unit of signal processing for reproducing data are recorded, each of the plurality of tracks being recorded with at least data and, as a preamble necessary for controlling the reproduction of the data, a separation pattern necessary for detecting a positional relationship between a reproducing head and the plurality of tracks in a track width direction and synchronization patterns for synchronization processing, the synchronization patterns being recorded in front and rear of the separation pattern in a running direction of the plurality of tracks, the reproducing apparatus comprising:
- a detecting section to detect the synchronization patterns in front and rear of the separation pattern;
- and
- an estimating section to estimate a head position of the separation pattern and the data based on a result of detecting the synchronization patterns by the detecting section at a time of reproduction in a first direction along the plurality of tracks and a time of reproduction in a second direction opposite to the first direction.
A reproducing apparatus reproducing a tape-like recording medium onto which a plurality of tracks that constitute a unit as one unit of signal processing for reproducing data are recorded, each of the plurality of tracks being recorded with data and, as a pattern necessary for controlling the reproduction of the data, a preamble including a separation pattern necessary for detecting a positional relationship between a reproducing head and the plurality of tracks in a track width direction, the unit being recorded plurally in parallel to each other along a running direction of the plurality of tracks, the reproducing apparatus comprising:
- one or more reproducing heads capable of reproducing signals across one or more tracks;
- an estimating section to estimate a positional relationship between the one or more reproducing heads and the plurality of tracks in the track width direction at a time of the reproduction using a reproduction signal of the separation pattern;
- and
- a forwarding amount calculating section to calculate a forwarding amount of the one or more reproducing heads at a time of switching the unit to be reproduced based on the positional relationship obtained by the estimating section.
A method of reproducing a tape-like recording medium onto which a plurality of tracks that constitute a unit as one unit of signal processing for reproducing data are recorded, each of the plurality of tracks being recorded with data and, as a pattern necessary for controlling the reproduction of the data, a preamble including a separation pattern necessary for detecting a positional relationship between a reproducing head and the plurality of tracks in a track width direction at a time of the reproduction, the unit being recorded plurally in parallel to each other along a running direction of the plurality of tracks, the method comprising:
- estimating a positional relationship between one or more reproducing heads capable of reproducing signals across one or more tracks and the plurality of tracks in the track width direction at the time of the reproduction using a reproduction signal of the separation pattern;
- and
- calculating a forwarding amount of the one or more reproducing heads at a time of switching the unit to be reproduced based on the estimated positional relationship.
