    摘要： A tracking servo system for a magnetic recording and reproducing apparatus uses a flexible magnetic disk having thereon at least first, second and third tracks each of which includes a data track portion and a pair of servo track portions located on both sides of the data track portion. Tracking signals having different frequencies are recorded on the first, second and third servo track pairs. Servo and data heads are formed in a unitary structure. When the data head records an information signal on the second data track portion or reads out the recorded information signal therefrom, the servo head reads out the tracking signals recorded on the first and third servo track portions.

    摘要： A rotary disk including a recording and reproducing sheet, and a hub formed of hard material secured to a central portion of the sheet. The hub comprises a center opening adapted to receive a main spindle of a turntable of disk driving means, two planar surfaces arranged in an intersecting relation to each other and formed on a projecting wall portion of the center opening, and a resilient member located in a position facing the two planar surfaces for pressing the spindle against the two planar surfaces. Even if the recording and reproducing sheet of the rotary disk is a thin magnetic sheet, there is no risk of damage of the sheet. When the rotary disk is set on the turntable, the center of rotation of the rotary disk and the center of rotation of the turntable can be automatically brought into alignment with each other.

    摘要： A disc cassette (11) for containing a disc (18) for rotation equipped with a shutter (14a, 14b) for opening and closing head windows (13) in slot form. The shutter automatically opens when the disc cassette is mounted on a cassette drive apparatus and automatically closes when it is removed therefrom. The shutter is mounted in center openings (15a, 15b) of the disc cassette for rotation therearound and has locked to one end portion thereof a movable belt (22) which causes the shutter to rotate when it moves. The movable belt has fastened thereto a spring (29, 50) for moving the belt in sliding movement to close the shutter at all times when the disc cassette is removed from the cassette drive apparatus.

    摘要： An imaging and recording apparatus for electrically recording an optical image of a subject as an image information signal which facilitates memory access from an external device and prevents image information from being changed. Upon manipulation of a recording trigger switch, an image outputted from a camera signal processing circuit at that time is written into a semiconductor memory, then subjected to data compression in a data compression circuit, and stored in a semiconductor memory. It is now assumed that an external device not illustrated is connected to a connector and this external device orders taking in the image of the semiconductor memory. If at this time the semiconductor memory is writing an image, a state detection circuit detects the fact and inhibits the external device from taking in the image. Furthermore, while the external device is taking in the image of the semiconductor memory, the state detection circuit detects this fact. Even if the recording trigger switch is manipulated, an AND gate turns off in response to an output of the state detection circuit and inhibits image writing into the semiconductor memory.

    摘要： A video camera recorder having a watertight housing including a housing body, a housing bottom and a closure for closing an opening of the housing. The opening is watertightly closed by a watertight structure including an annular bead formed in the housing and a packing provided to the closure. An electronic view finder is watertightly isolated in a space defined between a partition wall, arranged within the housing, and the housing. A cover is provided between the closure and an electronic equipment, such as a video deck, disposed within the housing, and a packing is arranged between the housing and the cover so that the space surrounded by the cover and the housing is held watertightly. Alternatively, the gap between a portion of a video deck disposed in the housing and a housing is watertightly sealed, the portion of the video deck projecting from the housing the opening. A water absorbent or a water sensor is disposed in a recess formed in the housing.
