Interlaced magnetic recording storage system

A storage device system, comprising:

• an interlaced magnetic recording (IMR) storage medium;
• a vibration sensor;
• a magnetic recording head;
• and
• a storage device controller configured to:
• determine that write retry operations are performed while writing data to top tracks in a normal writing sequence on the IMR storage medium;
• determine that bottom track caching space is available responsive to determining that the write retry operations were performed;
• perform a vibration detection scheme to identify vibration events using the vibration sensor responsive to determining that the bottom track caching space is available;
• determine that a number of detected vibration events is above a predetermined threshold;
• and
• write data to the available bottom track caching space on the IMR storage medium responsive to determining that the number of vibration events is above the predetermined threshold.

One or more tangible computer-readable storage media encoding computer-executable instructions for executing on a computer system a computer process, the computer process comprising:

• determining that write retry operations are performed while writing data to top tracks in a normal writing sequence on an interlaced magnetic recording (IMR) storage device;
• determining that bottom track caching space is available responsive to determining that the write retry operations were performed;
• performing a vibration detection scheme to identify vibration events responsive to determining that the bottom track caching space is available;
• determining that a number of detected vibration events is above a predetermined threshold;
• and
• writing data to the available bottom track caching space responsive to determining that the number of vibration events is above the predetermined threshold.
