Abstract
According to one embodiment, a magnetic recording device includes a recording medium, a magnetic head including a light source, a light emitting element, and a sensor, and a controller including an inspection circuit which detects a height of a defect of the recoding medium based on output of the sensor, a memory recording the height of the defect, and a setting circuit which sets an upstream side record/reproduce prohibited sector on an upstream side of the defect, in a travel direction of the magnetic head, on a track of the recording medium on which the defect is present, and which sets a downstream side record/reproduce prohibited sector longer in track direction than the upstream side record/reproduce prohibited sector on a downstream side of the defect.
