Abstract
An information recording apparatus includes: a unit for applying a predetermined processing to record information divided into error correction units and generating processed record information including a plurality of record units; and a unit for recording, the processed record information on an information record medium; a unit for recording, after the recording of the processed record information, predetermined dummy information of an information amount corresponding for the plurality of record units, on the information record medium, subsequent to the processed record information recorded.
Claims48
An information recording method of recording record information comprising a plurality of ECC blocks, each of the ECC blocks comprising a plurality of data units to record the record information, on a recording medium, the method comprising the steps of:
- recording first record information;
- recording dummy information up to a part of a recording area for recording a next ECC block subsequent to last ECC block included in the first record information after the last ECC block is recorded;
- and
- starting second recording for recording second record information from an intermediate position of the next ECC block by using a part of the second record information.
An information recording apparatus which records record information comprising a plurality of ECC blocks, each of the ECC blocks comprising a plurality of data units to record the record information, on a recording medium, the apparatus comprising:
- a recording device which records first record information;
- a dummy information recording device which records dummy information up to a part of a recording area for recording a next ECC block subsequent to last ECC block included in the first record information after the last ECC block is recorded;
- and
- wherein the recording device starts second recording for recording second record information from an intermediate position of the next ECC block by using a part of the second record information.
An information recording apparatus which records record information comprising a plurality of ECC blocks, each of the ECC blocks comprising a plurality of data units to record the record information, on a recording medium in accordance with following steps:
- recording first record information;
- recording dummy information up to a part of a recording area for recording a next ECC block subsequent to last ECC block included in the record information after the last ECC block is recorded;
- and
- starting second recording for recording second record information from an intermediate position of the next ECC block by using a part of the second record information.
An information recording method of recording record information comprising a plurality of information units based on an error correction, on a recording medium, the method comprising the steps of:
- recording first record information;
- recording dummy information up to a part of a recording area for recording a next information unit subsequent to last information unit included in the first record information after the last ECC block is recorded;
- and
- starting second recording for recording second record information from an intermediate position of the next information unit by using a part of the second record information.
An information recording apparatus which records record information comprising a plurality of information units based on an error correction, on a recording medium, the apparatus comprising:
- a recording device which records first record information;
- a dummy information recording device which records dummy information up to a part of a recording area for recording a next information unit subsequent to last information unit included in the first record information after the last ECC block is recorded;
- and
- wherein the recording device starts second recording for recording second record information from an intermediate position of the next information unit by using a part of the second record information.
An information record medium recording record information comprising a plurality of ECC blocks, each of the ECC blocks comprising a plurality of data units to record the record information:
- first record information is recorded;
- dummy information is recorded up to a part of a recording area for recording a next ECC block subsequent to last ECC block included in the first record information after the last ECC block is recorded;
- and
- second recording for recording second record information is started from an intermediate position of the next ECC block by using a part of the second record information.
