摘要： A magnetic recording and reproducing apparatus arranged to use a magnetic tape. The apparatus operates to derive the current taken-up position of the magnetic tape from the signals that are proportional to the rotation frequencies of a capstan motor, a supply reel and a take-up reel. Only when the taken-up position is near the tape end, the apparatus activates LEDs (light emitting elements) for sensing the tape end and photo-transistors (light receiving elements), for sensing the tape end.

摘要： On the occasion of stopping the tape running at a high speed, a winding radius of the tape supply reel is detected to set the tape deceleration rate (a) on the basis of the detected winding radius of the supply reel. After the tape running speed is decelerated up to the allowable speed VL in the predetermined deceleration rate (a), the tape is stopped by effectuating the brake. Thereby, the tape can be driven at the speed higher than the allowable speed VL without generating any damage, enabling reduction of time required for the fast-forward/rewind operation. This can improve application flexibility by providing a couple of tape running modes at the first high speed V1 which is higher than the allowable speed VL and the second high speed V2 which is lower than the allowable speed VL. In addition, running of the tape can be ceased within the predetermined time t from the input of the stop command signal by specifying the maximum speed Vmax depending on the preset deceleration rate (a) and limiting the tape running speed with the maximum speed Vmax.

摘要： A digital information signal transmitting/receiving method and system having a transmitter for transmitting an encrypted digital information signal and a plurality of receivers for receiving the encrypted digital information signal from the transmitter. The transmitter simultaneously distributes a plurality of identification codes associated with the receivers at a time ahead of the digital information signal. The receivers detect whether a particular identification code assigned to the receiver was included within a received plurality of identification codes. When the particular identification code has been detected as having been received the received encrypted digital information signal is decrypted into the original digital information. In order to request that a particular identification code be included so as to allow access to a program, either one of the receivers or the recorders each generate an information request signal. The transmitter is responsive to the information request signals to add to the digital information signal at a time ahead of the digital information signal, identification signals for identifying the receivers or the recorders which generated the information request signals, thereby producing a transmission signal formed of those signals, and to distribute this transmission signal to the receivers. The recorders control the received information signal to be recorded in response to the identification signals received by the receivers.
