Abstract
A hybrid recording and/or reproducing apparatus can deal with a readout failure of all or part of AV information on a hard disk by restoring the record by using a backup record which has been saved on a tape, and also can expand the recording capacity as the whole system based on the combination of the hard disk and tape. The apparatus consists of a server which records and reproduces AV information on the hard disk, a tape unit which records and reproduces AV information on the tape, and a control system which controls to save all or part of the AV information to be recorded on the hard disk onto the tape simultaneously to or on expiration of a certain time after the recording of the AV information on the hard disk.
Claims25
A digital information recording and/or reproducing apparatus for recording and/or reproducing digital information including an audio signal and/or video signal, said apparatus comprising:
- first recording and/or reproducing means which records and/or reproduces the digital information on a nonlinear-access recording medium;
- second recording and/or reproducing means which records and/or reproduces the digital information on a tape recording medium having a recording capacity which is greater than or equal to the recording capacity of said nonlinear-access recording medium;
- and
- control means which controls said first and second recording and/or reproducing means such that the same digital information as the digital information recorded on said nonlinear-access recording medium is recorded onto said tape recording medium simultaneously to or on expiration of a certain time after the recording of the digital information onto said nonlinear-access recording medium.
A digital information recording and/or reproducing apparatus for recording and reproducing digital information including an audio signal and/or video signal, said apparatus comprising:
- first recording and/or reproducing means which records and/or reproduces the digital information on a nonlinear-access recording medium;
- second recording and/or reproducing means which records and/or reproduces the digital information on a tape recording medium having a recording capacity which is greater than the recording capacity of said nonlinear-access recording medium;
- and
- control means which controls said first and second recording and/or reproducing means such that when said nonlinear-access recording medium has its vacant area decreasing below a prescribed capacity, the digital information on said nonlinear-access recording medium is erased so that the erased area is added to the vacant area until the vacant area regains the prescribed capacity, and the digital information, which is erased from said nonlinear-access recording medium, is recorded onto said tape recording medium.
A digital information recording and/or reproducing apparatus for recording and reproducing digital information including an audio signal and/or video signal, said apparatus comprising:
- first recording and/or reproducing means which records and/or reproduces the digital information on a nonlinear-access recording medium;
- second recording and/or reproducing means which records and/or reproduces the digital information on a tape recording medium having a recording capacity which is greater than or equal to the recording capacity of said nonlinear-access recording medium;
- and
- control means which controls said first and second recording and/or reproducing means such that upon receiving record serializing command information inclusive of the order of delivery of the digital information reproduced by said first recording and/or reproducing means, the digital information recorded on said nonlinear-access recording medium is reproduced in compliance with the order of delivery indicated by the record serializing command information and recorded onto said tape recording medium.
A digital information recording and/or reproducing apparatus for recording and/or reproducing digital information including an audio signal and/or video signal, said apparatus comprising:
- first recording and/or reproducing means which records and/or reproduces the digital information on a nonlinear-access recording medium;
- second recording and/or reproducing means which records and/or reproduces the digital information on a tape recording medium having a recording capacity which is greater than or equal to the recording capacity of said nonlinear-access recording medium;
- and
- control means which controls said first and second recording and/or reproducing means such that the digital information of high access frequency is recorded on said nonlinear-access recording medium and the digital information of low access frequency is recorded on said tape recording medium.
A digital information recording and/or reproducing method for recording and/or reproducing digital information including an audio signal and/or video signal on a nonlinear-access recording medium and a tape recording medium having a recording capacity which is greater than or equal to the recording capacity of said nonlinear-access recording medium, said method comprising:
- a first step of recording the same digital information as the digital information recorded on said nonlinear-access recording medium onto said tape recording medium simultaneously to or on expiration of a certain time after the recording of the digital information onto said nonlinear-access recording medium.
A digital information recording and/or reproducing method for recording and/or reproducing digital information including an audio signal and/or video signal on a nonlinear-access recording medium and a tape recording medium having a recording capacity which is greater than the recording capacity of said nonlinear-access recording medium, said method comprising:
- a first step of, when said nonlinear-access recording medium has its vacant area decreasing below a prescribed capacity, erasing the digital information on said nonlinear-access recording medium so that the erased area is added to the vacant area until the vacant area regains the prescribed capacity, and recording the digital information, which is erased from said nonlinear-access recording medium, onto said tape recording medium.
A digital information recording and/or reproducing method for recording and/or reproducing digital information including an audio signal and/or video signal on a nonlinear-access recording medium and a tape recording medium having a recording capacity which is greater than or equal to the recording capacity of said nonlinear-access recording medium, said method comprising:
- a first step of, upon receiving record serializing command information inclusive of the order of reproduction of the digital information from said nonlinear-access recording medium, reproducing the digital information from said nonlinear-access recording medium in compliance with the order of delivery indicated by the record serializing command information and recording the reproduced digital information onto said tape recording medium.
A digital information recording and/or reproducing method for recording and/or reproducing digital information including an audio signal and/or video signal on a nonlinear-access recording medium and a tape recording medium having a recording capacity which is greater than or equal to the recording capacity of said nonlinear-access recording medium, said method comprising:
- a first step of recording the digital information of high access frequency on said nonlinear-access recording medium and recording the digital information of low access frequency on said tape recording medium.
