title = "Read performance of tunneling magnetoresistive heads",
abstract = "We discuss the read performance, including the off-track performance and noise characteristics, of TMR heads. A vortex-like sense current field in TMR heads creates insensitive zones in the free layer and affects the output voltage and effective read width. The 1/f noise in the MHz-order frequency range was observed. To achieve a low-noise TMR head for high-density recording with small junction area, a high-quality thin barrier is a key to obtaining low 1/f noise, as well as small R. A products to reduce the shot noise.",
