Abstract
A method of protecting data on a recording medium against an adjacent track erase (ATE) effect, and a recording medium having a program therefor are provided. The method includes accumulating a number of turns of write operations in respective sub-areas, wherein the recording medium is divided into a plurality of sub-areas; and rewriting data on a sub-area of which an accumulated number of turns of write operations is greater than a limited number of turns of write operations. Accordingly, before data written on an adjacent track can be damaged by the ATE effect, data is rewritten and safely preserved.
Claims15
A method of protecting data written on a recording medium in order to prevent weakening of the data by iterative write operations, the method comprising the steps of:
- accumulating a number of turns of write operations in respective sub-areas, wherein the recording medium is divided into a plurality of sub-areas;
- and
- rewriting data on a sub-area in which an accumulated number of turns of write operations is greater than a limited number of turns of write operations.
A computer-readable recording medium having embodied thereon a computer program for executing a method of protecting data written on a recording medium in order to prevent weakening of the data by iterative write operations, wherein the method comprises the steps of:
- accumulating a number of turns of write operations in respective sub-areas, wherein the recording medium is divided into a plurality of sub-areas;
- and
- rewriting data in a sub-area in which an accumulated number of turns of write operations is greater than a limited number of turns of write operations.
A method of protecting data written on a recording medium of a hard disk drive, comprising the steps of:
- accumulating a number of turns of write operations in a portion of a recording area of the recording medium;
- and
- rewriting data in the portion of the recording area if the number of turns of write operations exceeds a predetermined value.
