Abstract
Systems and methods are disclosed for dynamically adjusting parameters used during a read operation to reduce stress on a read head. In certain embodiments, an apparatus may comprise a read head configured to read data stored to a data storage medium, and a control circuit that controls a parameter of the read head influencing the read head's ability to accurately read data. The control circuit may be configured to extend the working lifespan of the read head by monitoring a read performance of the read head, and adjusting the parameter to reduce the read performance when the read performance is greater than a first threshold.
Claims25
An apparatus comprising:
- a read head configured to read data stored to a data storage medium;
- a control circuit that controls a parameter of the read head influencing a read performance corresponding to the read head's ability to accurately read data, the control circuit configured to extend the working lifespan of the read head by:
- monitor the read performance of the read head;
- and
- adjust the parameter to reduce the read performance when the read performance is greater than a first threshold.
A method comprising:
- reading data stored to a data storage medium using a read head;
- controlling a parameter of the read head influencing a read performance, corresponding to the read head's ability to accurately read data, to extend the working lifespan of the read head including:
- monitoring the read performance of the read head;
- and
- adjusting the parameter to reduce the read performance when the read performance is greater than a first threshold.
A memory device storing instructions that, when executed, cause a processor to perform a method comprising:
- reading data stored to a data storage medium using a read head;
- controlling a parameter of the read head influencing the read head's ability to accurately read data to extend the working lifespan of the read head including:
- monitoring a read performance of the read head;
- adjusting the parameter to reduce the read performance when the read performance is greater than a first threshold;
- adjusting the parameter to increase the read performance when the read performance is below a second threshold;
- and
- not adjusting the parameter to maintain the read performance when the read performance is neither above the first threshold nor below the second threshold.
