摘要:
A data recorder employs a disk record having a spiral track with either magnetically or optically sensible indicia. A normal mode of operation is to repeatedly scan one turn or circumvolution of the spiral track for emulating a circularly closed track. The recorder responds to received commands from a utilization device to tailor the disk access and recovery operations to the received command based upon command parameters and current status of the disk record. Electrical circuit and programming arrangements for effecting the controls are disclosed.
