Abstract
When the user enters a command to eject an optical disc from an optical-disc apparatus by operating an input unit, a CPU records information such as an operating mode and a location accessed immediately prior to ejection of the disc into a RAM unit as resume-function related information. The resume-function related information is then supplied to the optical disc to be recorded thereon by way of a write-in channel buffer, a switch, an ECC circuit, an RF & demodulation/modulation circuit and an optical head. Accordingly it is possible to make an access to a location on an optical disc accessed immediately prior to ejection of the disc from an optical-disc apparatus when the disc is reinserted into the optical-disc apparatus.
Claims72
A recording apparatus for recording information on a recording medium loaded therein, comprising:
- recording means for recording information to a designated location on said recording medium;
- ejecting means for ejecting said recording medium;
- storage means for storing resume information indicative of at least a location on said recording medium accessed by said recording means immediately prior to ejecting said recording medium;
- and
- control means for controlling said recording means to record said resume information, stored in said storage means, on said recording medium;
- wherein said resume information includes operation information indicative of a type of operation to be executed and an execution time of said operation to be executed.
A method of recording information on a recording medium loaded into a recorder, comprising the steps of:
- recording information to a designated location on said recording medium;
- ejecting said recording medium;
- storing resume information indicative of at least a location on said recording medium accessed by said recorder immediately prior to ejecting said recording medium;
- and
- controlling the recorder to record said stored resume information on said recording medium;
- wherein said resume information includes operation information indicative of a type of operation to be executed and an execution time of said operation to be executed.
A reproducing apparatus for reproducing information that had been recorded on a recording medium prior to ejection of that recording medium from a recorder, said apparatus comprising;
- reproducing means for reproducing information from a designated location on said recording medium;
- first control means for controlling said reproducing means to read out resume information from said recording medium indicative of at least a location on said recording medium accessed by said recorder immediately prior to said ejection of said recording medium;
- and
- second control means for controlling said reproducing means according to said resume information;
- wherein said resume information includes operation information indicative of a type of operation to be executed and an execution time of said operation to be executed.
A method of reproducing information that had been recorded on a recording medium prior to ejection of that recording medium from a recorder, comprising the steps of:

- wherein said resume information includes operation information indicative of a type of operation to be executed and an execution time of said operation to be executed.
A method of recording information on a recording medium loaded therein and reproducing information from that recording medium, comprising the steps of:
- recording information to a designated location on said recording medium;
- ejecting said recording medium;
- storing resume information indicative of at least a location on said recording medium at which information was recorded immediately prior to ejecting said recording medium;
- recording said stored resume information on said recording medium;
- reproducing information from a designated location on said recording medium;
- reading out resume information from said recording medium indicative of at least a location on said recording medium at which information was recorded immediately prior to said ejection of said recording medium;
- and
- controlling reproducing of information according to said
- resume information;
- wherein said resume information includes operation information indicative of a type of operation to be executed and an execution time of said operation to be executed.
A computer program for controlling a recorder to record information on a recording medium loaded into the recorder, so that the recorder:
- records information to a designated location on said recording medium;
- ejects said recording medium;
- stores resume information indicative of at least a location on said recording medium accessed by said recorder immediately prior to ejecting said recording medium;
- and
- controls the recorder to record said stored resume information on said recording medium;
- wherein said resume information includes operation information indicative of a type of operation to be executed and an execution time of said operation to be executed.
A computer program for controlling a reproducer to reproduce information that had been recorded on a recording medium prior to ejection of that recording medium from a recorder so that the reproducer:
- reproduces information from a designated location on said recording medium;
- reads out resume information from said recording medium indicative of at least a location on said recording medium accessed by the recorder immediately prior to said ejection of said recording medium;
- and
- controls the reproduction of information according to said resume information;
- wherein said resume information includes operation information indicative of a type of operation to be executed and an execution time of said operation to be executed.
