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.

摘要： An optical projection printing apparatus which can irradiate a mask with light from a first light source to focus the mask pattern on a resist of a semiconductor wafer in a highly accurate alignment by a first optical system including a projection lens. A wafer mark formed on the wafer to have a grating pattern shape is arranged to have its grating pitch direction located in the sagittal plane of the first optical system. The wafer mark is irradiated with the light coming from a second light source having a wavelength different from that of the first light source. Of the reflected light from the wafer mark, only the .+-. 1st order diffraction light is extracted by a filter and partially superposed on the mask in a transversely misaligned state so that the reflected light from the wafer mark may be focused by a second optical system. The aforementioned filter is disposed in the Fourier plane of the second optical system.
