Abstract

PURPOSE:To prevent stored information on a disk from disappearing by stopping a disk device right after sensing a P wave of an initial slight shock of an earthquake. CONSTITUTION:While a P-wave sensor 22 senses no P wave, normal damping is applied to a motor 18 via a brake 19 with the output 23 of a control circuit 1. When it senses the P wave, on the other hand, a brake controller 21 outputs a prescribed damping signal with the output 24 of the control circuit 1, and the motor 18 decreases its turning speed rapidly and stops.
