Abstract

PURPOSE: To record and reproduce data without causing the delay of a data transfer even when plural defective sectors exist by providing a means to temporarily store the data, a means to store the position information of the defective sector and a means to store the position information of an alternate source sector.
CONSTITUTION: To a recording medium, the fixed number of alternate sectors are provided for each data area in which a recording unit sector composed of data and additional information to indicate the condition of the data is composed of a definite number, and a buffer memory 72 to store the data, a defective sector position information storage part 75 to store the position information of the defective sector and an alternate source position information storage part 76 to store the position information of the alternate source of the alternate sector are provided in a recording and reproducing device 78. For example, for a data format, one block is composed of a data area 1 composed of the definite number of recording sectors and an alternate area 2 composed of plural recording sectors to execute the alternate recording of the defective sector at the data area 1. Thus, even when plural defective sectors exist, without causing the delay of the data transfer, the data can be recorded and reproduced.
