PURPOSE:To efficiently and accurately perform the positional adjustment of a sensor for detecting positioning of a magnetic head provided on the titled magnetic disk driving device into the outermost circumferential track by enabling the sensor to be positionally adjusted by an adjusting screw screwed on a chassis. CONSTITUTION:An extension part 9d of the sensor 9 is insertedly fitted to a holder 14 via a sensor holding part 14a, and this holder 14 is mounted on a riser part 1a of the chassis 1 with a fitting part 14b situating outside. Then an adjusting screw 15 is screwed into a screw hole 1b of the chassis 1 after conforming a fitting hole 14d formed on the holder 14 to the screw hole 1b formed on the riser part 1a of the chassis 1 in their positions. Since the fine positional movement of the sensor 9 can be facilitated by turning clockwise or anticlockwise this adjusting screw 15, the relative positional adjustment of the sensor with a douser 11 is accurately feasible.
