摘要： The disclosed erasing apparatus serves for erasing a signal from individual recording tracks of a magnetic recording medium. A soft magnetic and high permeability member forms a magnetic circuit which passes through a magnetic head and the recording medium. A suitable arrangement causes either the magnetic head or the high permeability member to produce a magnetic field for erasing the signal.

摘要： A video system comprising a video camera and a recording device to record video signals obtained by the video camera. The recording device includes a video tape recorder (VTR) which may be combined with the video camera when recording and otherwise may be combined with a reproduction unit. Mode switches in the VTR are changed over depending on the combination desired. When the VTR is used with the camera, the combination records sound, video signal and controls signals on a tape wound around a drum. A system control circuit controls various motors and solenoids control operation of the VTR. Power supply to the system is controlled by a power source switch in the VTR, which element provides "OFF", "STANDBY I" and "STANDBY II" modes. Delay elements operate in the two standby modes. When the power source switch is in either standby mode, loading is done automatically. One standby mode provides power to a rotating system and the other mode provides no power. The delay elements provide different delay times for each mode so that triggering of the camera can be made with due consideration for the start up time of the rotating system. The built-in delays are effective in conserving power.

摘要： A video system includes a video camera for obtaining image signals, and a video recorder for recording the image signals. Driving power provided in the recorder, for loading a tape over a recording drum, is transmitted to the video camera after the tape is fully loaded on the drum. Movable parts in the video camera such as an automatic focus adjusting mechanism, can then be driven by the driving power source in the recorder.

摘要： In the magnetic recording and reproducing apparatus disclosed, a loading arrangement displaces magnetic tape between a position where the tape's running path from a tape supply member to a take up member relative to a recording and reproducing arrangement makes it possible to record and reproduce and a position where such recording and reproduction is disabled. A transfer friction arrangement between a tape drive and the supply member or the take up member changes its frictional operation depending upon the tape running path controlled by the loading arrangement. According to a specific embodiment disclosed, the drive is shiftable between a direct direct mode when the tape is disabled from recording or playback and a slip torque transmission mode when the recording-playback is enabled.
