Included in the Prior Art Database: 2005-Feb-20
The control described herein constitutes an improvement on the circuitry for testing the translatory movement of a magnetic diskette into a disk drive disclosed in the IBM Technical Disclosure Bulletin 21, 4620-4623 (April 1979). A digital amplifier 100 (Fig. 2) is preferably used between the photoelectric device 24 and the Index terminal A in said publication, and a similar digital amplifier 102 is used between a photoelectric device 104 and the Index terminal H for the amplifier 102.
