Flying height control method of record medium drive and magnetic recording medium and head element and flying height control circuit of head element

摘要

Record medium (14), the groove where the magnetic domain which is established every bit is arranged (72) with the groove territory of the plural books which are formed (74) with, the groove territory (74) the land territory of the plural books which are arranged between the fellows (65) with is formed on the surface. The land territory (65) record medium (14) the even surface is formed on the surface. At the time of zero calibrations the heater forms the protrusion of the head element on the basis of heat. Protrusion of such head element is executed the land territory (65) with. The point of protrusion the land territory (65) contacts the even surface. Therefore, wear of the point of protrusion is controlled. The damage of the head element is evaded.
