Information recording/reproducing apparatus
An information recording/reproducing apparatus includes a registration unit that registers scheduling information to periodically record information; a recording unit that records the information on a recording medium based on the scheduling information; a reproduction unit that reproduces the information recorded on the recording medium; a deletion unit that deletes the information according to a deletion instruction from the recording medium; and an erasure unit that erases, when the number of times of reproducing the information according to the deletion instruction is zero, the scheduling information associated with the information from the registration unit.
1. An information recording/reproducing apparatus, comprising:
a registration unit that registers scheduling information to periodically record information;
a recording unit that records and stores the information on a recording medium based on the scheduling information;
a reproduction unit that reproduces the recorded information stored on the recording medium on an output device;
a deletion unit that deletes the recorded information stored on the recording medium according to a deletion instruction; and
an erasure unit that automatically erases the scheduling information used for recording the recorded information when the recorded information is deleted according to the deletion instruction and when the recorded information has not been reproduced once on the output device.
2. A scheduling information automatic erasure method performed by an information recording/reproducing apparatus which records information on a recording medium and reproduces the information recorded on the recording medium, the scheduling information automatic erasure method comprising:
registering scheduling information to periodically record information;
recording and storing the information on the recording medium based on the scheduling information;
deleting the recorded information on the recording medium according to a deletion instruction; and
automatically erasing the scheduling information used for recording the recorded information when the recorded information is deleted according to the deletion instruction and when the recorded information has not been reproduced once on an output device.
3. A non-transitory computer readable storage medium storing a program including a process to be executed by a computer, the process comprising:
registering scheduling information to periodically record information;
recording and storing the information on a recording medium based on the scheduling information;
deleting the recorded information on the recording medium according to a deletion instruction; and
automatically erasing the scheduling information used for recording the recorded information when the recorded information is deleted according to the deletion instruction and when the recorded information has not been reproduced once on an output device.
4. The non-transitory computer readable storage medium according to claim 3 , wherein the information includes video information of a television broadcasting program,
the scheduling information includes a day of a week, a time window, and a channel number for recording the video information, and
the erasing erases the scheduling information in which the day of the week, the time window, and the channel number are used for recording the video information and whose recorded information is deleted are matched respectively as the scheduling information.
