Title: Information memory device
Inventor: OGAWA MASAHARU
IPC: G11B21/08
Filed: 1987-06-29
Abstract: PURPOSE:To rapidly perform tracking to a track in the neighborhood of a targeted track, by detecting tracking deviation, controlling the track transversal speed of the tip part of a head, and then, switching control to tracking control again. CONSTITUTION:When the tracking deviation occurs at the tip part of the head while the tracking control is performed, the tracking deviation is detected, and the tracking control is interrupted, and deceleration is applied controlling the track transversal speed of the tip part of the head. Afterwards, the tracking control is restarted after the fact that the speed is decelerated to a level possible to perform track pull-in is detected by a tracking control means 30. Therefore, the runaway of the head can be prevented from occurring in a case where the tracking deviation occurs, etc., and the tip part of the head can be pulled in to the center of the track in the neighborhood of the targeted track immediately without using an external scale. In such a way, it is possible to obtain an information memory device being operated at high speed and with high reliability.

IPC: G03C1/00
Filed: 1980-11-14
Abstract: PURPOSE:To obtain a dye image, by adding a specified alkoxynaphthol compound and a hydroquinone derivative to a silver halide photographic sensitive material. CONSTITUTION:A photosensitive material contains an alkoxynaphthol compound represented by the formulaIin which R1 is 1-4C alkyl or 2-4C alkoxyalkyl, and a hydroquinone derivative represented by the formula II in which R2 is halogen, 1-6C alkyl, 6-10C aryl, or 2-6C alkoxyalkyl.
