Method of determining size of error and write control method for hard disc drive, hard disc drive using the write control method, and media storing computer programs for executing the methods

摘要

A method of determining a size of an error generated in a servo sector, a write control method of controlling whether to write data to data sectors successive to a servo sector according to the size of the error generated in the servo sector therein, a HDD using the write control method, and a recording media storing computer programs for executing the methods. A method of determining a size of an error generated in a servo sector of a HDD includes: reading servo information from the servo sector in which the error was generated; and determining the size of the error by a number of corresponding bits that differ from each other between the read servo information and a normal servo information.
