Method and apparatus for adjusting asymmetric recording signals |
摘要 |
In a magnetic recording system, an asymmetry detector reverses the phase of a read, single-frequency test signal to indicate to a micro-controller whether recording signal asymmetry is present. Upon detecting such asymmetry, the micro-controller causes a current source coupled to the recording head to adjust a write current to correct the timing of a written data signal.
