Abstract
A method of forming a read head. The method includes forming first and second read sensors that are substantially trapezoidal in shape. A first read measurement is performed on a storage medium using the first read sensor. A second read measurement is performed on the storage medium using the second read sensor. Based on a comparison of the first and second read measurements to a predetermined quantity, either the first read sensor or the second read sensor is selected to be operational in a data storage device.
Claims15
A method of forming a read head, the method comprising:
- forming first and second read sensors that are substantially trapezoidal in shape;
- performing a first read measurement on one or more storage media using the first read sensor;
- performing a second read measurement on the one or more storage media using the second read sensor;
- and
- selecting either the first read sensor or the second read sensor to be operational in a data storage device based on a comparison of the first and second read measurements to a predetermined quantity.
A method comprising:
- forming a plurality of read sensors with each of the plurality of read sensors having a substantially trapezoidal shape;
- performing read measurements on one or more storage media using each different one of the plurality of read sensors;
- and
- selecting one of the plurality of read sensors to be operational in a data storage device based on a comparison of the read measurements of the different ones of the plurality of read sensors to a predetermined quantity.
