-
Patent number: 4074332Abstract: A digital circuit and method for measuring magnetic tape skew of magnetic tape units by recording on two channels of a reference tape a digital bit pattern of alternate pairs of zeros and ones.Digital logic circuitry, which detects this information on a reference tape when read from a magnetic tape unit to be tested, feeds the digital information on one channel to a shift register which is sampled by a clocking signal derived from the other channel. The digital bit pattern indicated at the output stages of the shift register will identify the existance of any excessive lag or lead skew.Type: GrantFiled: May 27, 1976Date of Patent: February 14, 1978Assignee: Litton Business Systems, Inc.Inventor: Frank T. Innes
