Information recording apparatus and information recording method
View Patent ↗A disclosed information recording apparatus includes an erasing unit configured to erase prerecorded information on recording media capable of being colored and decolored by heat; a recording unit configured to record information on the recording media from which the prerecorded information is erased; and a control unit configured, when a recording request is received, to cause the recording unit to start recording information on a first one of the recording media and to cause the erasing unit to start erasing prerecorded information on a second one of the recording media.
1. An information recording apparatus, comprising:
an erasing unit configured to erase prerecorded information on recording media capable of being colored and decolored by heat;
a recording unit configured to record information on the recording media from which the prerecorded information is erased; and
a control unit configured, when a recording request is received, to cause the recording unit to start recording information on a first one of the recording media and to cause the erasing unit to start erasing prerecorded information on a second one of the recording media.
2. The information recording apparatus as claimed in claim 1 , wherein the control unit is configured to cause the erasing unit to erase prerecorded information on the first one of the recording media before the recording request is received.
3. The information recording apparatus as claimed in claim 1 , wherein
the erasing unit includes a heating device configured to heat the recording media; and
the control unit is configured to start heating the heating device when the recording request is received.
4. The information recording apparatus as claimed in claim 1 , further comprising:
a cooling mechanism configured to cool the recording media from which the prerecorded information is erased.
5. The information recording apparatus as claimed in claim 1 , further comprising:
a conveying mechanism configured to convey the recording media from the erasing unit to the recording unit.
6. The information recording apparatus as claimed in claim 1 , further comprising:
a temporary storing mechanism configured to temporarily store the recording media, from which the prerecorded information is erased, before the recording request is received.
7. The information processing apparatus as claimed in claim 6 , wherein the temporary storing mechanism is configured to temporarily store at once a plurality of the recording media from which the prerecorded information is erased.
8. An information recording method, comprising:
a first step of starting to record information on a first recording medium when a recording request is received; and
a second step of starting to erase prerecorded information on a second recording medium when the recording request is received.
9. The information recording method as claimed in claim 8 , wherein the second step includes a step of starting to heat a heating device for erasing the prerecorded information on the second recording medium when the recording request is received.
10. The information recording method as claimed in claim 8 , wherein the first step and the second step are started at substantially the same time.
11. The information recording method as claimed in claim 8 , further comprising:
an erasing step of erasing prerecorded information on the first recording medium before the recording request is received.
12. The information recording method as claimed in claim 8 , further comprising:
a cooling step of cooling the second recording medium from which the prerecorded information is erased.
13. The information recording method as claimed in claim 11 , wherein in the erasing step, prerecorded information is erased from a plurality of recording media before the recording request is received.
