Abstract
According to one embodiment, a method of adjusting a magnetic recording and reproducing device is a method of adjusting a magnetic recording and reproducing device incorporating a heat-assisted magnetic recording head and a magnetic disk, and the method includes performing a first write operation at a first position on a recording surface, measuring a first error rate at a second position different in radial position from the first position, performing a second write operation and then measuring a second error rate, obtaining a first difference between the first error rate and the second error rate, measuring a third error rate at the first position, performing a third write operation and then measuring a fourth error rate, calculating a second difference between the third error rate and the fourth error rate, comparing the first difference with the second difference and determining a change in flying height.
