気デイスク装置。 a pickup for detecting shock and vibration; an amplifier for amplifying the output signal of the pickup;
Level determining means for outputting first, second and third control signals when the voltage level output from the amplifier exceeds a first, second and third level, respectively, and recording and displaying the voltage level. a power control means for turning off the main power of the apparatus in response to the first control signal; and a write/read inhibiting means for inhibiting write and read operations in response to the second control signal; go-home control means for inhibiting the seek operation of the positioner fixing the magnetic head in response to the third control signal and retracting the magnetic head from the data area of the disk; and the level determination means for controlling the shock and vibration. 1. A magnetic disk device comprising: inhibition canceling means for determining damage and returning each of the control/inhibition means to a normal operating state when detecting stoppage for a predetermined period of time or more.
