Abstract: In a system for controlling a machine tool (12) by a tool controller (10) under the supervision of a central data processor (11), in which the controller (10) transforms the data provided by the central processor (11) into a format compatible with the machine tool (12), e.g., clock pulse encoded data format suitable for writing into and reading out of a serial storage magnetic memory device (12), a test system is provided wherein the central processor (11) includes a simulation of the controller (10). This simulated controller gives the processor the capability of simulating and applying to the tool controller (10) data in a format equivalent to that normally applied to the tool controller from the tool (12) itself, e.g., a clock encoded data read output. The simulated controller also provides the central processor with the capability of receiving from the tool controller a tool control output in the format compatible with the tool control, e.g., clock encoded data and changing said data into an original format usable in the central processor.

Abstract: SAFEGUARDING OF DATA RECORDED ON DISK BY TUNNEL ERASE MAGNETIC HEAD ASSEMBLY Apparatus is provided for the safeguarding of data recorded on disk and diskettes by tunnel erase magnetic head assembly which comprise a read/write transducer for magnetically recording data along tracks on said disk and a pair of magnetic erase transducers adjacent to the read/write transducer for limiting the width of the recorded data. The apparatus for safeguarding the recorded data comprises apparatus for sensing the activation of the erase and/or read/write transducer and apparatus responsive to such sensed activation for determining if the activation is erroneous.

Abstract: A CENTRAL PROCESSOR SUPERVISED MACHINE TOOL CONTROLLER SYSTEM HAVING A SIMULATION OF THE TOOL CONTROLLER IN THE CENTRAL PROCESSOR FOR TEST PURPOSES In a system for controlling a machine tool by a tool controller under the supervision of a central data processor, in which the controller transforms the data provided by the central processor into a format compatible with the machine tool, e.g., clock pulse encoded data format suitable for writing into and reading out of a serial storage magnetic memory device, a test system is provided wherein the central processor includes a simulation of the controller. This simulated controller gives the processor the capability of simulating and applying to the tool controller data in a format equivalent to that normally applied to the tool controller from the tool itself, e.g., a clock encoded data read output. The simulated controller also provides the central processor with the capability of receiving from the tool controller a tool control output in the format compatible with the control tool, e.g., clock encoded data and changing said data into an original format usable in the central processor.
