ABSTRACT:
Apparatus for generating self-clocking data of a predetermind format simulating control information recorded on a dynamic magnetic medium storage device. The data generator includes means for simulating servo clock signals and encoding means for producing formatted data signals having jitter and phase relationship to the servo signals which are worst-case rather than random. The apparatus is utilized to test data recovery circuits independently of the storage device.
