FIELD: one-time record carrier, capable of preserving the data record condition, method for preserving condition of data record on aforementioned carrier and device for recording and/or reproduction of aforementioned carrier.
SUBSTANCE: in the method for preserving data record of one-time record carrier, data is firstly recorded on one-time record carrier. Then, data about condition of record, representing occupied areas, are generated and recorded in temporary defect control area allocated in the carrier. After that finalization command is received to preserve the condition of data record of the data carrier. Then, in response to the finalization command, given data is recorded in temporary defect control area, to prevent additional recording of data onto the carrier. Therefore, condition of data record of finalized one-time record carrier may be preserved.
EFFECT: increased efficiency.
