Abstract: A pick-up device for reading out information which has been recorded on a magnetic medium. The device comprises a substrate and a layer of soft magnetic material overlying a surface of the substrate, the easy axis or direction of magnetization being normal to the surface and the magnetic material having properties capable of having magnetic bubble domains generated and propagated therein, so that when the pick-up device is used to read out information from a magnetic medium, patterns of magnetic domains are formed in the layer of magnetic material corresponding to the patterns of the recorded information. Although the magnetic material is of the type capable of having magnetic bubble domains generated and propagated therein, there is no need to provide the usual bias field for maintaining the bubble domains or for providing domain-transport or domain-annihilating fields. In one use of the pick-up device, light is transmitted through the substrate and through the layer of magnetic material to be reflected from a layer of light-reflective material back through the magnetic material and the substrate, whereby the polarization of the reflected light is rotated, relative to the polarization of the transmitted light, by an amount determined by the patterns of magnetic domains formed in the layer of magnetic material. Hence, the recorded information can be optically read from the magnetic medium. In another use of this device, a magnetoresistive head is disposed on the substrate, the resistance of this magnetoresistive head being varied as a function of the patterns of magnetic domains formed in the layer of magnetic material.

Abstract: PROBLEM TO BE SOLVED: To provide an imaging apparatus of which the cost can be reduced by reducing the storage capacity of a memory by reading an image of an imaging range corresponding to zoom magnification from a solid-state image pickup element at the time of digital zooming, and to provide an imaging method. SOLUTION: At the time of digital zooming, a digital zoom setting part 22 sets a vertical imaging range of a CMOS image sensor 13 in accordance with zoom magnification, and the CMOS image sensor 13 images the set imaging range. When the zoom magnification is changed, a maximum exposure time of the CMOS image sensor 13 is operated on the basis of the zoom magnification before and after the change so as to prevent a shutter signal after the change from interfering with a read signal before the change, and the exposure time of the CMOS image sensor 13 is set so as not to exceed the operated maximum exposure time.
