Abstract
According to one embodiment, a method of adjusting a heat-assisted magnetic recording and reproduction device including a heat-assisted magnetic recording head and a heat-assisted magnetic recording medium provided with a lubricant on a recording surface thereof, and the method includes operating the heat-assisted magnetic recording head on the recording surface, and measuring a build-up product generation 10 time until the lubricant fills between the recording surface and the heat-assisted magnetic recording head to generate a build-up product, and setting a cleaning time interval for cleaning the build-up product based on the build-up product generation time.

A method of adjusting a heat-assisted magnetic recording and reproduction device comprising a heat-assisted magnetic recording head and a heat-assisted magnetic recording medium provided with a lubricant on a recording surface thereof, the method comprising:
- operating the heat-assisted magnetic recording head on the recording surface, and measuring a build-up product generation time until the lubricant fills between the recording surface and the heat-assisted magnetic recording head;
- and
- setting a cleaning time interval for cleaning the build-up product based on the build-up product generation time.
A heat-assisted magnetic recording and reproduction device comprising:
- a heat-assisted magnetic recording head;
- a heat-assisted magnetic recording medium provided with a lubricant on a recording surface thereof;
- a build-up product cleaning controller which controls cleaning of a build-up product generated between the heat-assisted magnetic recording head and the recording surface;
- and
- a cleaning time interval controller which controls a cleaning time interval for the build-up product, and
- wherein the cleaning time interval is set based on a build-up product generation time, which is obtained by operating the heat-assisted magnetic recording head on the recording surface and measuring the build-up product generation time until the lubricant fills between the recording surface and the heat-assisted magnetic recording head.
