摘要： A thin-film magnetic head for magnetic recording and reproducing apparatus includes a lower insulating layer deposited on a substrate and including a lower magnetic core, an intermediate insulating layer deposited on the lower insulating layer and including front and rear intermediate magnetic cores, and an upper insulating layer deposited on the intermediate insulating layer and including an upper magnetic core. The magnetic cores make up a magnetic circuit which has a magnetic gap defined between the lower magnetic core and the front intermediate magnetic core or between the front intermediate magnetic core and the upper magnetic core. A multiturn coil is embedded in the intermediate insulating layer to surround the rear intermediate magnetic core. The lower, intermediate, and upper insulating layers have respective flat surfaces including respective surfaces of the lower, intermediate, and upper magnetic cores. The lower, intermediate, and upper insulating layers are joined to each other through the flat surfaces.

摘要： A series of film-containing cassettes are placed in projecting positions and thereafter in rewinding positions. First and second take-up reels are arranged to be axially movable between first and second positions. An elongate film guide member is movable between an active position in which the guide defines a straight threading path between the cassette occupying the projecting position and the take-up reel occupying the first position and a normally inactive position in which the guide is clear of the threading path. In the film threading mode, the leading end of film is driven through the straight threading path and taken up by the take-up reel. A film handling mechanism is provided between the opposite ends of the threading path. Upon completion of film threading, the movable elongate guide is restored to the inactive position and the film handling mechanism is brought into operation to engage the film with an aperture plate. Upon completion of film projection, the cassette and the first take-up reel which occupy the projecting and first positions, respectively, are shifted to the rewinding and second positions, respectively. A subsequent cassette is shifted to the projecting position and the second take-up reel occupies the first position. Film threading of the subsequent film cassette is effected simultaneously with rewinding of the previous cassette.
