Filed: 1991-12-20
Abstract: The present invention is intended to improve the track recording density and track density of a magnetooptic recording medium to prevent the deterioration of characteristics due to the variation of reproducing power. After recording information signals on a magnetooptic recording medium having at least a reproducing layer, an intermediate layer and a record hold layer, the direction of magnetization of the reproducing layer is turned in the direction of an initializing magnetic field. The reproducing layer is irradiated with a laser beam and a reproducing magnetic field is applied to the same simultaneously to heat the reproducing layer in a temperature distribution so that a region remaining in an initialized state, a region to which information signals are transferred and a region magnetized in the direction of the reproducing magnetic field are formed. Magnetic signals are read from the region of the reproducing layer to which information signals have been transferred.

Title: System for changing the speed of conveyed sheets while holding register
Inventor: MARSCHKE CARL R
IPC: B65H29/12
Filed: 1991-03-26
Abstract: A system for changing the speed of conveyed sheets (10) while maintaining the sheets in register including a speed changing belt (18) operating at a constant speed (V1) to present a radial outer surface portion which travels over a cylindrical guide (23) and into tangent contact with the surface of the sheet travelling at a speed equal to the velocity of the incoming sheets. A portion of the speed changing belt includes an acceleration lobe (30) positioned to engage the trailing portion of the sheet and to provide a continuously increasing radius at the tangent contract portion as the belt (18) travels around the pulley (23) whereby the outer surface velocity of the lobe and the sheet in contact therewith continuously increase from the incoming speed to a desired second speed (V2). The constant velocity speed changing belt (18) requires only a simple constant speed drive and the speed change lobe (30) attached to the belt requires only a relatively small increase in the effective radius of the belt around the cylindrical guide such that unacceptable vertical displacements of the sheet from the plane of travel are obviated. Only the mass of the sheet or other product being conveyed (and an upper holddown idler roll if used) is subject to acceleration (or deceleration) forces as all the machine drive components run at constant velocity during the speed change, thereby minimizing the overall inertial effects.
