Title: Composite magnetic head
Inventor: FUJIOKA YOSHIHARU
IPC: G11B5/265
Filed: 1983-03-15
Abstract: PURPOSE:To attain recording/reproduction with very high density and to prevent mutual interference of magnetic flux, by providing a notch for both of a write/ read gap and an erase gap and separating a write/read magnetic head core from an erase magnetic head core with a nonmagnetic layer. CONSTITUTION:The 1st magnetic head core 21 and the 2nd magnetic core 22 have the same thickness as a couple and a write/read gap 23 made of a nonmagnetic substance is formed between opposing surfaces of the cores 21, 22. The same 1st notch 24 is formed on both sides of the gap 23, i.e., at both sides of the cores 21, 22 respectively and the width of the gap 23 is limited to a value Tw with the 1st notches 24. In recording signals on a medium with the magnetic head, the magnetic head is slided on the medium and the recording is done over the width Tw of the gap 23 with a write/read magnetic head core 26. Immediately after the recording, recorded both ends of the width Tw are erased with an erase magnetic head core 36 following to the core 26. Thus, a track recorded at a width narrower than the width Tw exists on the medium.

Title: Exposure device
Inventor: ISOHATA JUNJI
IPC: G03F7/20
Filed: 1986-02-28
Abstract: PURPOSE:To prevent the deviation of a baking pattern caused by a yawing by a method wherein the yawing of a stage when the stage, on which the substance such as an original sheet or the material to be exposed and the like are mounted, is shifted is detected and it is automatically corrected. CONSTITUTION:If the reading of laser interferometers 61 and 62, namely, the amount of movement in X-direction of a substrate stage 4 from a reference position are X1 and X2, and the distance between the interferometers 61 and 62 is L, a yawing angle theta can be computed from theta=tan<-1>(X1-X2)/L. Accordingly, the first theta-table 41 and the second theta-table 42 are rotated respectively when the stage is corrected in the direction of rotation in order to correct the yawing angle theta after a stepping movement has been performed and also to position the substrate to a mask when the accuracy of positioning in the direction of rotation is poor. Besides, as occasion demands, the substrate stage 4 can be positioned more precisely by correcting the position in X-Y direction by shifting the X-Y table 44.
