Signal recording apparatus and signal recording method

A signal recording apparatus for recording sequential data onto a recording medium having a data recording area divided into sectors of predetermined recording units with each sector provided with a physical block address and a management area for managing recorded data, the apparatus comprising:

• recording means for dividing the sequential data into units corresponding to the sectors, providing each unit with a logical block address, and recording each unit provided with the logical block address onto the sector of the corresponding physical block address;
• defective sector detection means for reading out the physical block address of the sector on which one unit is recorded in recording the one unit of the sequential data by the recording means, then judging whether the read physical block address is correctly read or not, and detecting whether the sector on which the one unit is recorded is a defective sector or not;
• address control means for causing the recording means to record the one unit onto the sector of the physical block address read by the defective sector detection means when no defective sector is detected by the defective sector detection means, and for causing the recording means to record the one unit onto the sector of the physical block address next to the physical block address read by the defective sector detection means when the defective sector is detected;
• storage means for storing the physical block address of the defective sector when the defective sector is detected by the defective sector detection means;
• and
• address recording means for recording the physical block address of the defective sector stored in the storage means into the management area of the recording medium after all the sequential data are recorded onto the recording medium to complete recording.
