摘要： A magnetic head actuator for displacing a magnetic head on a rotary magnetic head drum in a magnetic recording and reproducing apparatus includes a hollow cylindrical yoke housing a permanent magnet and a central pole therein, providing a magnetic circuit having an air gap. A support shaft axially movably extends through the yoke and has opposite ends positioned outside of the yoke. A coil bobbin is attached to the end of the support shaft which is positioned outside of the open end of the yoke. The coil bobbin supports a coil which is axially movably positioned in the air gap. Two parallel resilient suspension support wings are mounted on the yoke and attached respectively to the opposite ends of the support shaft. A magnetic head holder supporting a magnetic head is mounted on the end of the support shaft near the bottom of the yoke. When the coil is energized, the coil bobbin and hence the support shaft are axially moved to displace the magnetic head to a desired track on a magnetic tape around the rotary magnetic head drum. Since the support shaft is supported by the parallel suspension support wings, the magnetic head is held in good contact with the magnetic tape and prevented from being tilted out of a desired azimuth with respect to the magnetic tape. The magnetic head which is positioned near the bottom of the yoke is free from leakage fluxes from the magnetic circuit.

摘要： A magnetic recording and reproducing apparatus has a supply reel and a take-up reel around which a magnetic tape is to be wound. A first tape guide is provided in the vicinity of a rotary head at the supply reel side and a second tape guide in the vicinity of the rotary head at the take-up reel side. The first and second tape guides are movable in directions of a width of the magnetic tape. A detector detects a height of each of the first and second tape guides. A count value corresponding to the detected height of at least either the first or the second tape guide is obtained by a counter. The height of at least either the first or the second tape guide is adjusted so that the count value becomes equal to a reference value. The count value is set to a specific value when the detected height becomes a reference height corresponding to the reference value after the magnetic tape has been wound around the supply and take-up reels.

摘要： In apparatus for recording/reproducing a composite video signal on and from a rotary recording medium (1), the field of the composite video signal is detected and only odd or even field signal is delayed by one half (H/2) a horizontal scanning period so that the composite video signal is changed to a modified composite video signal which is recorded on the rotary recording medium (1) together with a field distinguishing signal (Sf) produced using the result of the field detection. The field distinguishing signal (Sf) is arranged to be located at a given time position with respect to a predetermined vertical sync signal of every one frame period of the recording signal on a rotary recording medium (1) driven and rotated at a rotational period equal to the vertical scanning period of the composite video signal. This field distinguishing signal is extracted from a reproduced signal obtained in reproduce mode so that field switching is effected using the reproduced field distinguishing signal thereby delaying only even or odd field signal, which has not been delayed on recording, for obtaining a composite video signal having sync signals which with regular interlaced scanning can be performed.

摘要： An apparatus for processing audio signals is provided with a memory for storing the audio signals. The audio signals are written in the memory at write addresses in the memory. The audio signals are read from the memory in accordance with reading addresses at a speed lower than a speed for writing the audio signals into the memory. It is determined whether an amount of audio signals stored in the memory and not yet read therefrom is increasing. The write addresses are then updated when the amount of audio signals not yet read is increasing. When small signals levels of which are lower than a reference level are detected among the audio signals, updating of the write addresses of the small signals may be halted.
