Drum assembly for a magnetic recording and reproducing apparatus

摘要

A drum assembly for carrying a plurality of rotary recording and reproducing heads of a magnetic recording and reproducing apparatus recording and reproducing a signal on and from a magnetic recording medium in a rotative manner. The drum assembly comprises a stationary drum fixed on a magnetic recording and reproducing apparatus body, a rotary body supported on the stationary drum in a rotative manner for carrying the plurality of rotary recording and reproducing heads, amplifying means disposed in the rotary body for amplifying the reproducing signal supplied from the plurality of rotary recording and reproducing heads, and signal transmitting means at an interface between the stationary drum and the rotary body for transmitting the recording signal from a recording and reproducing circuit to the plurality of rotary recording and reproducing heads and for transmitting the reproduced signal reproduced by the rotary recording and reproducing heads and amplified by the amplifying means to the recording and reproducing circuit.
