Abstract
A cassette tape recorder used with a tape cassette loaded therein comprises a pair of capstans, a motor, a power transmission mechanism, a first and a second magnetic head assembly, a moving mechanism and a magnetic head assembly operation switching circuit. The motor rotates selectively in one or the other direction at the same constant speed and with the same characteristics. The transmission mechanism is coupled to the capstans and to the motor for transmitting the rotation of the motor to the capstans to cause simultaneous rotation of the capstans in one or the other direction at the same constant speed. The first and second assemblies move between a first position in contact with the tape in the loaded tape cassette and a second position spaced apart from the tape. In the first position, the first assembly can record magnetic signals in some track of the tape driven in one direction or reproduce magnetic signals from the track, and the second assembly can record magnetic signals in other track of the tape driven in the other direction or reproduce magnetic signals from the track. The moving mechanism moves the two assemblies simultaneously and in the same direction. The circuit electrically selects and renders operative the first assembly when the tape is driven in one direction and selects and renders operative the second assembly when the tape is driven in the other direction.
