A magnetic disk drive having at least a contact magnetic head and at least a magnetic disk (4) including a recording area (9) and an abrasion promoting area (10) is preliminarily operated after the magnetic head and the magnetic disk are mounted thereon and prior to a normal recording and reproducing operation thereof, to abrade the magnetic head by using the abrasion promoting area. The abrasion promoting area (10) is provided by making its surface roughness larger than that of the recording area (9) of forming a lubricant film on only the recording area. By preliminarily abrading the magnetic head by means of the abrasion promoting area, a contact of the magnetic head with the magnetic disk (4) is improve and a desired recording and reproducing characteristics of the magnetic disk drive is obtained. <IMAGE> |
