Patent ID: 7325093

Claim:
A recording method comprising: reading a signal recording bitmap (SRB) created for managing data recorded on a recording medium as units of a first recording, segment the SRB and first recording segment being recorded in different areas of the recording medium; detecting said first recording segment corresponding to a specified file allocation table (FAT) sector according to first data which is designated to be recorded as units of said FAT sector smaller than the first recording segment into said recording medium, said first data to be stored in the specified FAT sector; discriminating from said created signal recording bitmap whether it is possible to read data from said first recording segment, said created signal recording bitmap indicating whether data has ever been written to the first recording segment independent of a present state of the first recording segment; reading second data stored in said first recording segment and temporarily recording said second data to a memory when in said discriminating step it is determined that it is possible to read data from said first recording segment; recording the first data to a position associated with a part of said first recording segment recorded in said memory in units of said FAT sector; and recording said second data that was temporarily recorded in said memory to said first recording segment in said recording medium, a part of said second data being revised by said first data.
