Abstract
A recording device for digital signals which is able to record high quality signals for a prolonged time on a magnetic tape by effectively utilizing the production equipments or components of the conventional magnetic tape. The present recording device for digital signals records data of the DV format on a magnetic tape 8 mm in width. For example, data of two tracks of the DV format are recorded on a sole track of the magnetic tape of 8 mm width with a data pattern remaining unchanged.
Claims16
A magnetic recording apparatus for digital signals comprising:
- recording data generating means for generating recording data associated with a digital recording format applied to a first magnetic tape of a pre-set tape width;
- and
- recording means for recording the recording data generated by said recording data generating means on a second magnetic tape having a tape width broader than that of said first magnetic tape;
- said recording means recording at least two tracks of the recording data in the digital recording format generated by said recording data generating means in succession on a sole track formed on said second magnetic tape.
A magnetic recording method for digital signals comprising:
- generating recording data associated with a digital recording format applied to a first magnetic tape of a pre-set tape width;
- and
- recording at least two tracks of recording data in said digital recording format on a sole track formed on a second magnetic tape having a tape width broader than that of said first magnetic tape.
A magnetic reproducing apparatus for digital signals comprising:
- reproducing means for reproducing recording data associated with a digital recording format applied to a first magnetic tape of a predetermined tape width from a second magnetic tape of a tape width broader than said predetermined tape width carrying said recording data;
- and
- data processing means for processing the recording data reproduced by said reproducing means;
- said reproducing means reproducing at least two tracks of the recording data of said digital recording format in succession from a sole track formed on said second magnetic tape.
A magnetic reproducing method comprising:
- reproducing at least two tracks of data in the digital recording format in succession from a sole track formed on a second magnetic tape carrying recording signals of the digital recording format applied to a first magnetic tape of a predetermined tape width, said second magnetic tape having a tape width broader than said predetermined tape width;
- and
- processing reproduced recording data.
