Abstract:
A recording method for recording information onto an information recording disk including a volume space capable of recording an audio/video (AV) file and a non-AV file,the recording method comprising the steps of:(a) determining whether a file to be recorded is the AV file or the non-AV file;(b) generating file management information including attribute information indicating whether the file is the AV file or the non-AV file in accordance with the detention result;(c) when it is determined that the file is tie non-AV file, recording the non-AV file into the volume space based on a first defect management method in which, when a defective sector is detected, an Error Correcting Code (ECC) block including the defective sector is replaced with another ECC block; and(d) when it is determined that the file is the AV file, recording the AV file into the volume space based on a second defect management method which is different from the, first defect management method,step (d) further includes the steps of:(d-1) recording AV data of the AV file in at least one recording area in the volume space, the at least one recording area is an area of continuous sectors of at least one ECC block; and(d-2) recording in the volume space the file management information including at least one first location information, second location information, at least one first identification information and second identification information;the at least one first location information specifying the location of an AV extent which is an area of continuous sectors of AV data in the at least one recording area,the second location information specifying the location of a padding extent which is an area of continuous sectors in the at least one recording area, the padding extent being an area from an end of the AV extent to a boundary of an ECC block,the at least one first identification information indicating an AV extent, andthe second identification information indicating a padding extent,step (d-1) fur includes the step of, when a defective sector is detected, skipping at least one sector including the defective sector and recording the AV data of the AV file into at least one sector following the skipped at least one sector.
