Apparatus and method for controlling hard disk drive-locating position by counting sectors |
摘要 |
An error-tolerant apparatus and method are disclosed for controlling disk read/write actions on a hard disk drive having no identification (ID) information in the data sectors. A servo sector number is calculated each time a servo sector pulse is input. When a target servo sector number is the same as the calculated servo sector number, a determination is made whether a data read/write error exists. If there is no error, a servo sector is detected and the calculated servo sector number is updated. If there is an error, the calculated servo sector number is maintained. Afterwards, a data read/write error is detected when the target servo sector is detected, the data sector number in the maintained servo sector is set to a number of data sector units to be skipped, and the disk read/write operation is performed from the data sector next to the previous sector.
