Shock resistant, high reliability rotating magnetic storage device and method

An information recording method in a data storage apparatus, comprising:

• performing at least a write operation onto a recording medium;
• receiving output from an acceleration sensor, the acceleration sensor output indicating that a shock has been detected;
• outputting a latch signal at a first level during a write inhibit period, wherein the write inhibit period is selected based on the acceleration sensor output;
• outputting a write gate signal at the first level when a write permission is given;
• and
• enabling a write onto the recording medium when the latch signal is at a second level other than the first level and when the write gate signal is at the first level.

An information recording method in a storage apparatus comprising a head for performing at least a write operation onto a recording medium, and an acceleration sensor for detecting a shock, the method comprising:

• receiving an output from the acceleration sensor;
• determining whether the acceleration sensor output exceeds a predetermined threshold;
• if the acceleration sensor output exceeds the predetermined threshold, determining a time span in which the output of the acceleration sensor exceeds the predetermined threshold;
• selecting a write inhibit period based at least in part on the time span in which the output of the acceleration sensor exceeds the predetermined threshold;
• and
• prohibiting writing to the recording medium during the write inhibit period.
