Title: Recording method for magneto-optical recording medium and device therefor
Inventor: YAMAGUCHI ATSUSHI
IPC: G11B11/10
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To allow recorded signals to be stably reproduced under the same conditions through a varied domain length by recording a signal in a part of a unit domain length, reducing the essential recording domain length, and ensuring full transfer and expansion of the magnetic domain to the reproducing layer even if the domain length is varied. SOLUTION: In the case where a signal '1' is recorded in a unit domain length 1T, it is divided so that '1' is recorded in the front half and the '0' in the rear half. In this case, one period of alternating field is applied to the unit domain length 1T with a magnetic head, with the magnetic field of S polarity applied to the front IT/2 and with that of N polarity to the rear 1T/2. As a result, the essential recording domain length is confined to 1T/2, the reproducing conditions have only to be optimized to the domain length of 1T/2, the distribution of leak magnetic fields is small in the domain, and the leak magnetic fields in the opposite direction formed outside the domain is also small; therefore, the transfer and the expansion of the magnetic domain can be fully performed in the reproducing layer.

Title: Dot line printer
Inventor: YAGETA KOICHI
IPC: B41J35/04
Filed: 1995-01-27
Abstract: PURPOSE: To prevent the lowering of printing quality by always ensuring the opposed relation between printing pins and holes even when the drive cycle of printing hammers is increased by providing the holes opposed to the printing pins of a ribbon separator so as to shift the same with respect to the centers of the printing pins in a dot line printer. CONSTITUTION: The positions of the hole of the ribbon separator of a central part are shifted by ΔL from the positions of printing pins 6 toward the downstream side in a paper feed direction. Therefore, an ink ribbon 8 sags downwardly by the resistance of the printing pins 6 during printing caused by the running of the ink ribbon 8 and, even when the separator 9 being in contact with the ribbon 8 is together lowered by the sagging of the ribbon 8, since the positions of holes are preliminarily shifted by ΔL from those of the printing pins 6 in expectation of this phenomenon, core shift does no become much.  When the ribbon 8 is raised by the resistance of the printing pins 6 during printing caused by the running of the ribbon 8 and the separator 9 being in contact with the ribbon 8 is together raised, the hole positions of the separator 9 at a central part are shifted by ΔL from the positions of the printing pins 6 toward the upstream side of the feed direction to prevent core shift.
