A rotary die cutter for cutting a series of irregular-shaped blanks from a continuous web. The disclosure invokes an interface to define an information service within the reusable framework. In the preferred embodiment, using the clock signal, a highly accurate, variable time delay is generated between the rotation of a master recording spindle and the recording of sector header data on a master disk mounted on the spindle.
