ABSTRACT:
The present invention enables recovery of data reading, even when thermal asperities or defective media will make it impossible to increase the number of retries or to read the data, occur in the AGC/PLL part. In a device for writing and reading information, when an error occurs in the region of the recording media where the AGC/PLL signal is written, and if that information is written continuously to several sectors, then data reading is performed by using the AGC/PLL of the following sector, without performing a retry, or by performing a minimum number of retries.
