Abstract

A computer-controlled technique for aligning the heads of a diskette drive, utilizing a commercially available "cat's-eye" alignment diskette, is described. An electronic card conditions the diskette drive's readback signal, as the signal is generated by reading the spinning diskette. The signal is digitized, and the digitized values are supplied to a controlling computer for processing and presentation to the operator performing head alignment. This technique represents an improvement over the prior method of the operator observing the readback signal on an oscilloscope and visually determining the degree of head alignment.
