Abstract: An information transmitting system capable of two way communication, suitable for use in transmitting information signals between a central control unit and a plurality of terminal apparatus units. Each terminal apparatus unit may be located at a different passenger seat in an aircraft, a train, a bus, or the like. The signals transmitted from each terminal apparatus to the central control unit are transmitted by way of two channels. In one operating mode, one channel is used as a random access channel, and the other is used as a polling channel. When polling transmission is not effected, the polling channel is used as a second random access channel, so that the system may efficiently transmit many information signals on two random access channels.

Abstract: A method of position detection on a recording medium is performed by moving the recording medium alternately in normal and reverse directions, while searching for a target position, and decreasing the travel speed of the recording medium with each change in direction. Immediately after a target position has been finally passed, a report signal of the search completion is generated, thereby shortening the search time.
