Abstract

A computer-based system, such as a value printing system, has a host data processor having at least one disk drive that includes a first read/write head for reading data from and for writing data to a removable data recording disk. The system further includes a printer, coupled to the host data processor and responsive thereto, for printing indicia indicative of a monetary value. The system further includes a removable data recording disk having an integral data processor including a memory for storing data expressive of a monetary value associated with printed indicia. The integral data processor further includes a second read/write head coupled to the recording medium for communicating with the host data processor through the first read/write head.
