Abstract
A read channel module including an input, a location module and a generation module. The input is configured to receive a read-back signal from a rotating storage medium. The location module is configured to determine a location to insert a first imitation defect within the read-back signal. The first imitation defect imitates a first defect. The generation module is configured to (i) selectively generate the first imitation defect, and (ii) insert the first imitation defect in the read-back signal at the determined location.
Claims20
A read channel module comprising:
- an input configured to receive a read-back signal generated by a read head, wherein the read-back signal is generated by the read head based on a reading from a rotating storage medium;
- a location module configured to determine a location to insert a first imitation defect within the read-back signal, wherein the first imitation defect imitates a first defect;
- and
- a generation module configured to
- selectively generate the first imitation defect, and
- insert the first imitation defect in the read-back signal at the determined location.
