Abstract
Circuit for generating a write disable signal in response to an applied shock force. Angular displacements which indicate an excessive shock force are detected, and signal processed to determine whether or not a displacement will result from the shock force exceeding a threshold level. Low frequency displacements are de-emphasized, while higher frequency displacements in a passband of interest are integrated to obtain a displacement function. The displacement function is compared in a threshold detector with a reference threshold displacement level. Displacements which exceed the established threshold displacement will generate a write disable signal.
