Magnetic tape tracking control apparatus and method, magnetic tape format, recording medium and program

A magnetic tape tracking control method for a magnetic tape tracking control apparatus for controlling tracking of tracks on a magnetic tape by a rotary head, comprising:

• a first generating step for encoding an inputted video signal to generate said video data;
• a second generating step for generating search video data on the basis of said video data generated in said first generating step;
• and
• a recording step for recording, on said tracks, said video data generated in said first generating step, said search video data generated in second generating step and positional information associated with a recording position of said search video data.

A recording medium storing a computer-readable program for a magnetic tape tracking control apparatus for controlling tracking of tracks on a magnetic tape by a rotary head, comprising:

• a first generating step for encoding an inputted video signal to generate said video data;
• a second generating step for generating search video data on the basis of said video data generated in said first generating step;
• and
• a recording step for recording, on said tracks, said video data generated in said first generating step, said search video data generated in second generating step and positional information associated with a recording position of said search video data.

A program for causing a computer for controlling tracking of tracks on a magnetic tape by a rotary head to execute:

• a first generating step for encoding an inputted video signal to generate said video data;
• a second generating step for generating search video data on the basis of said video data generated in said first generating step;
• and
• a recording step for recording, on said tracks, said video data generated in said first generating step, said search video data generated in second generating step and positional information associated with a recording position of said search video data.

A magnetic tape tracking control apparatus for controlling tracking of tracks on a magnetic tape by a rotary head, comprising:

• a first generating means for generating a first number corresponding to a position of said tracks, recorded with search video data;
• a second generating means for generating a second number corresponding to a position of one of said tracks;
• and
• a comparing means for comparing said first number with said second number to control tracking on the basis of a result of the comparison.
