摘要: Channel parameters for a magnetic readback channel are optimized by detecting signal that is recorded on medium. The contains plurality of predetermined-length control fields. Each field arranged between two user data fields and at least one transition. At selected parameter, such as frequency system clock, gain the channel, equalization response signal, and/or an amplitude asymmetry based information contained in field.
