摘要： The present invention resides in a washing device constructed by a conveyer of a carrying-in side arranged in a frame, a reservoir lower portion having plural rails for holding the work and an ultrasonic generator arranged in this frame, each reservoir upper portion united with this reservoir lower portion, a raising-lowering device for raising and lowering each reservoir upper portion, an arm mechanism for work conveyance, a moving device for controlling advancing and retreating movements of the arm mechanism, a movable device for controlling a swinging return of the arm mechanism, and a conveyer of a carrying-out side for conveying a processed work. The conveyer and the rail of each reservoir lower portion are approximately arranged on the same face. The work is horizontally moved through this conveyer and the rail and is washed and dried by utilizing the union of each reservoir lower portion and each reservoir upper portion. Accordingly, the work is simplified and made at high speed and is facilitated by performing the washing, the processing and the movement in the horizontal movement. A dividing type using the reservoir lower-upper portion is used, and ultrasonic washing is performed by supplying a fluid to the reservoir and the function of the ultrasonic device is enlarged.

摘要： The present invention uses a magnetic recording medium equipped with those magnetically readable recording servo pits which are preformed on a magnetic recording medium and have different magnetic characteristics from those of a recording magnetic film, detects magnetically a tracking signal or preformat signals such as sync signals, address signals, and the like, from the magnetic flux distribution (leakage magnetic field) occurring at edges of each of the servo pits using a magnetic head, makes servo control of the position of the magnetic head by the detected tracking signal and records or reads magnetically the data along the center of a track. In the magnetic recording medium of the present invention, magnetically readable, wobbled servo pits or sync pits, track address pits and data pits are preformed on the magnetic recording medium, these pit portions have locally different magnetic characteristics from those of the recording magnetic film and have a magnetic film structure wherein saturated magnetization is smaller than at other portions or the magnetic film is removed locally. These preformed pits can be read magnetically by detecting the local magnetic field (leakage magnetic field) generated at their edges by the magnetic head.
