Abstract

In magnetic readback the head to media spacing has a determining effect on the strength of the readback signal from the magnetic media, the wear of the head and the media and the overall performance of the recording system. In the case of perfect contact between the head and the media, the readback signal is the strongest, but so is also the head and media wear. As the head to media spacing increases the wear decreases but so does the signal strength.
