Abstract
A method for controlling read velocity in a disk device is provided. When reading data on the disc, the method first reads each SYNC of blocks to form an ECC code, read data to decode, and checks and corrects decoded data to generate decoded errors. The type of decoded errors are classified and counted to form reference parameters of a rule base. A fuzzy engine checks if the counting number exceeds the threshold of the parameter, and executes the operation of the rule to control read velocity and enhance the data transfer rate in the disk device.
Claims18
A method for controlling read velocity in a disk device, comprising the steps of:
- forming an ECC code;
- reading data to decode;
- correcting decoded data with the ECC code;
- classifying and counting decoded errors;
- using a fuzzy engine to check if each count exceed a specific threshold and if conditions of execution rules are met;
- and
- executing the execution rule where the conditions are met.
