  • Cateye-signal intercept detector for aligning a read-write head above a computer data storage disk
    Patent number: 4321636
    Abstract: A cateye-signal intercept detector for aligning a read-write head above a computer data storage disk. The detector used in conjunction with a standard disk having two adjacent cateye-type head alignment tracks thereon. The subject invention automates the detection of each intercept in the cateye-signal so that associated processing equipment responsive to the output signal produced can measure the read-write head disk alignment automatically.
