Disk player which avoids sound failure resulted from retry of data reading

摘要

A disk player reads data read from a disk after temporary storage in a memory and outputs the read data and is capable of preventing the memory from becoming empty by a retry operation for reading data, thereby avoiding a sound failure. When an address whose data is not correctly readable is present on a disk, the address information of that address is stored, and when the same disk is played again, the data reading operation for the new address is performed before the amount of remaining data in the memory becomes too small at the time the next reading address is address whose data is unreadable based on the address information. When at least the same disk is played again, therefore, the memory may not become empty, thus preventing a sound failure from occurring.
