摘要： A first magnetic core has a first portion that determines the track width, a second portion extending from the first portion substantially vertically, a third portion that extends from the second portion substantially vertically and is longer than the first track width, and a fourth portion extending from the third portion substantially vertically. The first to fourth portions form a substantially rectangular ring-like shape with its portion between the first and second portions being notched. A second magnetic core has a fifth portion longer than the first track width, a sixth portion extending from the fifth portion substantially vertically, and a seventh portion extending from the sixth portion substantially vertically. The fifth to seventh portions form substantially the shape of letter C. The first and second magnetic cores are joined to each other so that the first and fifth portions are joined through a gap spacer, the outer circumferential surfaces of the first and fifth portions form a surface to be brought into slidable contact with a magnetic medium, and at least parts of the third and seventh portions and at least parts of the fourth and sixth portions are respectively stacked and joined to each other.

摘要： A camera capable of operating in a red-eye prevention mode. The camera has an electronic flash device which is activated by a drive circuit in synchronization with the exposure. The electronic flash device also serve as a pre-light-emission device capable of performing pre-light-emission for the purpose of preventing red-eye effect. When it is judged from the photographing condition that red-eye effect may occur, a controller activates the electronic flash device to effect a pre-light-emission for reducing the size of pupils of eyes of a person to be photographed, before the main flashing which is executed in synchronization with the exposure.

摘要： A high magnetic head for floppy disk drives that can prevent crosstalk between magnetic cores. Two nonmagnetic material pieces are joined with two magnetic material pieces, respectively, and track grooves and a winding groove are formed on a surface of each of the two magnetic material pieces. The nonmagnetic material pieces are joined together to form a core block with those surfaces facing each other on which the grooves are formed. The core block is cut to a plurality of front core assemblies. The core assembly includes a magnetic circuit having a magnetic gap, and nonmagnetic spacer members which do not form a magnetic circuit, thereby preventing crosstalk between the magnetic cores constituting the composite type magnetic head.

摘要： In a magnetic head in which first and second core halves are disposed on the entry and leaving sides of a magnetic recording medium, respectively, one of the first and second core halves is provided with a first edge for limiting a data track width and second edges which are disposed on both sides of the first edge and are inclined by a first angle with respect to the first edge. The other core half is provided with a third edge which is opposed to the first edge and is equal in length to the first edge. The other core half is also provided with fourth edges disposed on both sides of the third edge and inclined by a second angle with respect to the third edge. The data recording is made in the magnetic field between the first and third edges. Furthermore, the recording is made on both sides of the data track by the magnetic fields between the second and fourth edges so that erasure of old data can still occur despite deviation of the positions of the new and old data tracks. On both sides, data which has an azimuth with respect to the data recorded on the data track is not reproduced and there is no adverse effect.
