Abstract: A low cost easy use alignment device is used to perform radial alignment of a read/write head in a floppy disk drive of a personal computer. The computer holds the read/write head at the alignment track of a special alignment disk. The alignment track as well as the outermost track and an inner track contain all binary "1" bits while all other tracks contain no data. The alignment device contains an amplifier to amplify the signal read by the read/write head. The signal is detected at the output of the first read amplification stage of the disk drive. The alignment device amplifier signal is displayed on an indicator. A dot/bar display driver with light emitting diodes connected to the outputs is used as an indicator. The stepper motor or head carriage assembly is moved to maximize the indicator signal which corresponds to the optimum radial alignment of the read/write head.
