摘要： A tension servo apparatus includes a brake member which may apply a braking force to a reel system. The brake member is coupled to a tension arm which is displaced in response to a tape tension and may slide on the outer periphery of said reel system in accordance with the displacement of the tension arm or the rotation of the reel system.

摘要： A discrete 4-channel stereo recording and reproducing system which is based on a regular matrix type 4-channel stereo system and compatible with both of a regular matrix system and a CD-4 type 4-channel stereo system. In the audio frequency band, the same encoding as that in the regular matrix system is performed and, in the carrier frequency band, encoding for satisfying the compatibility with existing systems is achieved. The decoding is intended to improve the sound image location and separation in the reproduced sound field from CD-4 type stereo signals and automatic switching of a decoding circuit for the regular matrix type signals is achieved.

摘要： The present invention is to increase the carrier level so as to improve the S/N ratio when the factor T.sub.93, T.sub.T or T.sub.Q is small in level. When the level is low, noises are apt to be offensive to a listener's ear, but the reproducing level may be judged by the low level of T.sub..SIGMA., T.sub.T or T.sub.Q. Accordingly, the low level of T.sub..SIGMA. or T.sub.T is detected to raise the carrier level, and to reduce an FM demodulation noise and hence to improve the total S/N ratio.
