Abstract
Abstract A plurality of recording heads records, on a magnetic medium, the signals derived from a corresponding plurality of transducers arranged in an array. Each recording head records a respective transducer signal on a separate track of the recording medium which is movable relative to the recording heads and relative to a readout means. The readout means comprises a plurality of linear transducers each of which extends across all of the recording tracks. The orientation of each linear transducer is greater than 0* with respect to movement of the recording medium and each linear transducer is at an angle with respect to one another. The signal provided by each linear transducer accordingly represents energy impinging upon the transducer array from a specified direction dependent upon the orientation of the linear transducer means. A scanning function is simulated by a rotation of the linear transducer means.
