* In magnetic recording systems, it has been reported that sufficient SNR was obtained with a narrow track width, using a spin-valve head and metal-evaporated tape. In order to apply this to a helical-scan tape system, techniques for writing narrow tracks and reading them exactly were required. However, the degree of mechanical accuracy demanded was too(More)
A giant magnetoresistive (GMR) head in tape-recording systems is affected by the electrostatic discharge (ESD) between the sensor and magnetic shields. Hence, Pt-doped Al<sub>2</sub>O<sub>3</sub> was developed as a dissipative gap material to reduce the ESD current. Pt chips were sputtered on an alumina target to vary the film resistance. The decay time of(More)
