Title: Optical recording medium and tracking control method using said medium
Inventor: YASUKAWA KAORU
IPC: G11B7/24085
Filed: 1988-06-30
Abstract: PURPOSE:To expand the locking range of tracking control by arranging 1st and 2nd reflection marks while the position in the circumferential direction is deviated at both sides while clipping the center line of the recording track and arranging inversely in the radial direction of the base between adjacent recording tracks. CONSTITUTION:The 1st reflection marks 51 of each recording track and the 2nd reflection marks 52 are made adjacent with each other and the recording layer 3 without provision of each mark is made adjacent among adjacent recording tracks Tk-1, Tk, Tk+1. Thus, a difference signal P1-P2 corresponding to the deviation from the recording track center is obtained by the reflection luminous quantity from the 1st and 2nd reflection marks 51, 52 and when an optical head is moved in the radial direction of an optical recording medium to evade the deviation based on the difference signal P1-P2, it is possible to control properly the moving direction of the optical head and its moving quantity regardless of the quantity of the deviation of the convergence spot.

IPC: C21C1/10
Filed: 1979-12-14
Abstract: PURPOSE: To prevent the lowering in molten metal temp., make melting furnace and ladle last longer and make energy comsumption less by coating the spheroidizing material in a ladle with sand thereby suppressing the abrupt reaction during spheroidizing.  
     CONSTITUTION: After a spheroidizing material 4 comprising an Fe-Si-Mg alloy or the like is inserted into a ladle 3, the material 4 is coated with sand 6, thence molten metal 2 is poured into the ladle 3. It is equally well to put an inoculant 5, if necessary, after the insertion of the material 4, and coating the same with the sand 6. Namely, the drop of molten metal temp. occurs less because the sand 6 is used as a covering material. Hence, there is no need for beforehand making the molten metal temp. higher than necessary and for preheating the ladle 3, and this allows the melting furnace and ladle 3 to last longer. In addition, this saves fuel and electric power and further provides a good yield of the material 4.
