Abstract
A data converting method includes counting for each bit pattern among bit patterns that a data segment of a specific number of bits can assume, the number of data segments that have the bit pattern, where the data segments are segments of write_data written to a storage medium storing two types of bit values among which a first value has a higher error occurrence rate than a second value; correlating a bit pattern selected as a conversion source pattern, from among the bit patterns in descending order of count results, with a bit pattern selected as a conversion target pattern, from among the bit patterns in descending order of quantities of the second value respectively included in the bit patterns; and converting for each conversion source bit pattern, data segments having the conversion source bit pattern, into converted data segments having the correlated conversion target bit pattern.
