A rotating storage apparatus is provided for high recording reliability in an
environment
in which a shock or vibration exists. Provided are means for outputting a shock
out signal (SO) if an output from an acceleration sensor exceeds a predetermined
threshold, a latch circuit 21 for outputting a latch signal at high level
during a predetermined write inhibit period after the shock out signal (SO) is
input, and a write gate signal (WG) which goes high when a write is enabled. A
write enable signal is generated by an AND circuit 23 having a NOT output
of the latch signal as well as the write gate signal WO as its inputs.
