摘要： A method for positioning a composite head comprising a control head and an audio head in a rotary head type magnetic video recording and reproducing apparatus at a precise spacing relative to a mounting position of the rotary head is disclosed. A video signal is recorded intermittently for each group of a predetermined number of video tracks on a reference tape and an audio signal is also recorded intermittently in association with the intermittently recorded video signal. The composite head is adjusted and positioned such that the intermittent relationship existing between a reproduced video signal and a reproduced audio signal is the same as the intermittent relationship existing between the video signal and audio signal during recording.

摘要： Two auxiliary heads are provided in addition to the two main heads for a helical scan video signal tape recorder. The vertical and horizontal positions of the auxiliary heads are determined so as to effectively reproduce a slow-motion picture from a magnetic tape on which the signals are recorded using the so called "azimuth" recording method. The output of each head is selectively supplied to a video signal demodulating circuit via a switching circuit.

摘要： An optical head which includes a movable bobbin having an objective lens and tracking coils for tracking operation, a carriage guided in such a manner to be able to move in the tracking direction and a state transformation mechanism for transforming the state of the bobbin and carriage between a first state, in which the objective lens can move in the tracking direction but the carriage does not move in the tracking direction, and a second state, in which the movable bobbin and the carriage moves in the tracking direction as one body. When effecting a tracking operation, the state transformation mechanism transforms the state of the bobbin and the carriage into the first state, in which the objective lens can move in the tracking direction but the carriage does not move in the tracking direction, and a tracking drive current is then made to flow through the tracking coils to perform the tracking operation. This results in that the objective lens is supported by a system of a single degree of freedom, of which characteristics are determined by the mass of the movable bobbin and the spring constant of the bobbin supporting means. In contrast, when effecting an access operation, the state transformation mechanism transforms the movable bobbin and the carriage into the second state, in which the bobbin and the carriage move in the tracking direction in one united body, and an access drive current is then made to flow through the tracking coils to effect the access operation. Thereby, tracking performance can be increased and a seeking operation can be performed at a high speed. Further, the tracking coil can be used to effect the access drive operation. Thus, there can be less weight of a movable part of the optical head and lower power consumption.

摘要： A tape cassette having a swingable cover adapted to cover and protect a tape stretched along the front side of the tape cassette, a cover locking member adapted to prevent swinging of the swingable cover by rotating in the thicknesswise direction of the tape cassette within a groove which is defined between the inner surface of one side wall of the swingable cover and the side wall of the box-like structure of the tape cassette and also between two side walls of the box-like structure which are on the extensions of the one side wall of the swingable cover and the above-mentioned side wall of the box-like structure. The groove serves also as a mis-insertion preventing groove for preventing the tape cassette from being inserted into the cassette holder in a wrong posture. According to this arrangement, it is possible to realize a compact construction while fulfilling all of the requisites for the tape cassettes.

摘要： In a recording/reproducing apparatus, a first support frame (22) supports a tape cassette (1), a second support frame (23) supports a tape guide drum (9) and loading rings (29), (30), (16), (17), and a third support frame (24) slidably supports the first support frame (22) and the second support frame (23). In a cassette loading operation, when the first support means (22) approaches the second support means (23) for a predetermined interval, a predetermined tape path is established by various loading posts, the tape guide drum (9) and the like. Then, the first support means (22) and the second support means (23) are slid together on the third support means (24) to be received compactly in the apparatus.

摘要： The invention provides an information recording/reproducing apparatus having a device for loading a cartridge internally holding an information recording medium, an opposing member directly facing the information recording medium at least in a recording mode, and a device for transferring the opposing member. When inserting the cartridge into the information recording/reproducing apparatus, the cartridge loading device transfers the cartridge at least in the direction of the thickness of the cartridge, and then the transfer device transfers the opposing member positioned outside an extended space in the direction of the thickness of the cartridge to a position at which the opposing member directly faces the information recording medium inside the extended space in the direction of the thickness of the cartridge.

摘要： A recording/reproducing apparatus comprising a tape winding device rotationally moving around a tape guide drum for pulling out a tape from a tape cassette and for wrapping the pulled-out tape on the tape guide drum. The tape guide drum advances into an opening portion of the tape cassette on tape loading, resulting in producing a moving space of the tape winding device, and the tape winding device is rotationally moved around the tape guide drum in the produced space between the tape guide drum and the casing section in response to the advancing movement of the tape guide drum. A casing section of the recording/reproducing apparatus and a member operatively associated with the casing section may either enter into the locus of the rotational movement of the tape winding device after the tape winding device is rotationally moved by a predetermined angle.

摘要： Disclosed is a tape cassette for short-time recording having an interchangeability with a long-playing standard tape cassette. The short-time cassette has the external size and functions substantially the same as that of the standard tape cassette. The casing of the short-time tape cassette is provided with a large aperture the area of which is made larger than that of an aperture formed in the bottom of the standard tape cassette, owing to the reduction in the diameters of the reel flanges. With this arrangement, it is possible to accommodate the mechanism including the tape path within the outside dimensions of the tape cassette, thus allowing miniaturization of the mechanism of the apparatus which handles the tape. At the same time, a perfect interchangeability between the short-time tape cassette and the standard tape cassette is obtained, so that users can operate both types of the tape cassette on an identical player such as a VTR.
