Abstract :
Media noise is treated as the random pulse modulation of averaged magnetization derivative. The modulation is of several types simultaneously: pulse position, shape, width, and amplitude. The theory of such modulations is presented. Bandwidth limitation in a readback transducer results in the transformation of these modulations into a single sideband modulation that mixes all types together
