Abstract
An implementation of a system disclosed herein provides a method of determining a frequency of baseline noise in a target or read sensor signal and rejecting a band of signals from the target or read sensor signal substantially around the frequency of the baseline noise, including devices to implement this method.
Claims22
A method comprising:
- determining a frequency of baseline noise in a target signal;
- and
- rejecting a band of signals from the target signal substantially around the frequency of the baseline noise.
A device, comprising:
- a baseline noise frequency detector configured to determine a baseline frequency of a reader baseline noise;
- and
- a band rejection filter configured to reject the baseline noise from a read sensor signal.
A method, comprising:
- positioning a read sensor head on a non-data zone of a disc drive;
- receiving a baseline signal from the read sensor;
- and
- determining a baseline frequency value of the baseline signal.
