Abstract
A method of optimizing design parameters of a data storage system in which a failure of products is caused by changes in the time required for using the products and characteristics of the products is pre-estimated. Design parameters used in a signal processing circuit in the pre-estimated failure condition are optimized and stored. A signal is processed using the design parameters optimized in the pre-estimated failure condition if errors occur due to changes in conditions of use of the data storage system. According to the method, the period and frequency of use of the data storage system can considerably be extended.

A method of optimizing design parameters used to operate a data storage system, the method comprising:
- determining and storing first design parameters to optimize the data storage system to operate while experiencing a general burn-in test condition;
- generating a progressive failure condition pre-estimated to occur in the data storage system;
- and
- setting and storing third design parameters to optimize the data storage system to operate while experiencing the generated pre-estimated progressive failure condition.
A method of applying optimized design parameters for use by a data storage system when processing a signal, the method comprising:
- applying first design parameters to be used by the data storage system to process a signal, the first design parameters being parameters that optimize the data storage system to operate while experiencing a general burn-in test condition;
- and
- applying third design parameters to be used by the data storage system to re-process the signal if errors occur in the data storage system using the first design parameters, the third design parameters being parameters that optimize the data storage system to operate while experiencing a progressive failure condition.
A method of applying optimized design parameters used in the operation of a data storage system when processing a signal in the data storage system, the method comprising:

- and
- storing the first and third design parameters for use by the data storage system.
A recording and/or reproducing apparatus to record and/or reproduce data with respect to a recording medium, comprising:
- a head to record and/or reproduce the data with respect to the recording medium;
