A NIST researcher has completed a study of high-frequency magnetic noise in commercial magneto-resistive recording heads. The study was done in collaboration with two private U.S. companies involved in the manufacture of disk drives and recording heads. The magnetic noise in the read sensors was measured over a frequency range from 0.1 GHz to 8 GHz. Magnetic noise is the component of noise due to thermal fluctuations of the magnetic layers used to sense the fields from data bits. These fluctuations scale inversely with the sensor size and, as the sensor dimensions shrink below 100 nm, can become the dominant source of noise. The peak magnetic noise level in 200 nm devices ...
