Methods of and apparatus for seeking a target address on a record medium.

摘要

A method of and an apparatus for seeking a target address having an appended error check code are disclosed. When seeking a target address on a record medium (1) on which the recorded data are divided into a plurality of blocks in correlation with an address for each block and an error check code for each address, the error check code to be appended to the address is formed from the target address. The target address and the error check code derived from the target address are compared with the address having the error check code reproduced from the record medium (1). When the result of such comparison has revealed that the error is within the symbol or bit number that can be corrected by the error check code, the address read from the record medium (1) is determined to be the target address.
