  • Abstract
    Digital magnetic information is recorded on a rotating disc thin film by a conventional tape recorder head. The information is read out using the longitudinal magnetic Kerr effect, and a 1.5- MHz bandwidth electronic system. The use of spatial filtering and a differential scheme yields a ratio of peak-to-peak signal to rms noise of 32 dB, which is very close to the shot noise limited case.
