Abstract:
A magnetic tape apparatus comprising:a magnetic head arranged to face a recording side of a magnetic tape having a servo area for head positioning; a head holding mechanism for holding the magnetic head and reciprocally move the magnetic head in a width direction of the magnetic tape; a head positioning mechanism for urging the head holding mechanism with a predetermined moving force; a main controller for driving the head positioning mechanism according to a servo information recorded on the magnetic tape and controlling operation of respective components of the apparatus such as the magnetic tape running drive apparatus; write control circuit provided adjacent to the main controller, for controlling to write a predetermined information transmitted from an upper node apparatus to the magnetic head; a shock sensor provided in the head holding mechanism for detecting a predetermined possible shock force applied to the head holding mechanism, and converts a detected shock into a predetermined signal; and a stop signal output circuit operating according to an output from the shock sensor, so as to supply a predetermined operation stop signal to the main controller and the write control circuit.
