摘要： A sensor unit having a sensor and an adjustment unit is welded to a vehicle. After the mounting of the sensor unit, a receiver unit externally receives modification information for modifying the load signal adjustment. Thereby, the load signal outputted from the sensor is adjusted by the adjustment unit responsive to the modification information to be externally outputted. Thus, alter the mounting of the sensor unit, the receiver unit receives the modification information, and the adjustment unit adjusts the load signal supplied from the sensor based on the modification information. This allows the sensor unit to unitarily have the sensor and the adjustment unit. Thereby, the adjustment unit can be modified by the modification information externally supplied. Accordingly, the sensor unit with the adjustment unit can be applied to various types of vehicles.

摘要： The present invention relates to a magnetic recording medium and a magnetic recording/reproducing apparatus for the same. In the magnetic recording medium there are provided a read/write region which permits modification of written data and a read-only region dedicated to the reading of data, which is used for reading only once writing is done. In recording servo information to a data format region of the magnetic recording medium, the time width of servo information in the read-only region is set shorter than that in the read/write region.

摘要： A invention relates to a disk medium and a method of writing data onto the disk medium. The disk medium is formatted in such a manner that: there are provided a plurality of track zones formed into segments of concentric circles separated from each other in radial directions of the disk; a plurality of servo areas are formed along lines which are located at intervals of substantially equal angle and which extend from the center of the disk toward the outer periphery across the track zones; the plurality of track zones each include a plurality of sector areas each provided with a data area; and the length (in bytes) of the data area in each sector area is varied depending on the track zone's location on the disk medium so that no servo area is located within any of data areas.
