PROBLEM TO BE SOLVED: To provide a method for overwriting data in a probe base data storage device wherein the data are represented by the existence/absence of a pit formed on a storage surface by a device probe. SOLUTION: Input data are encoded such that continuous bits of first values in coded input data are divided by at least one bit of another value. Overwritten data bits v<SB>0</SB>, v<SB>1</SB>, ... are generated from the coded input data b<SB>0</SB>, b<SB>1</SB>, ... used to overwrite data on the storage surface 4. The overwritten data bits are formula 1 with respect to i≥1 when a pit represents the first value in the data storage device, and are generated such that v<SB>0</SB>has the first value. The overwritten data bits are v<SB>1</SB>= b<SB>i-1</SB>with respect to i≥1 and are generated such that v<SB>0</SB>has another value. COPYRIGHT: (C)2004,JPO
