  • Magnetic read/write of reference track in contact start-stop testing of magnetic disks
    Patent number: 6157189
    Abstract: Methods and apparatus for testing a magnetic disk and a read head are provided. A reference track is written on the magnetic disk. The read head is scanned laterally with respect to the reference track while the magnetic disk is rotating. The reference track is sensed with the read head as the read head is scanned across the reference track to produce a scanned read signal that is representative of disk and read head performance. The scanned read signal may be processed to provide parameters such as track average amplitude, signal-to-noise ratio, and pulse width of write transitions.
