Tunneling magnetoresistive (TMR) heads have been observed to exhibit relatively large low-frequency noise. Observation in a saturating field reveals that a substantial part of this noise is of electrical origin. Two distinctly different electrical no

Write current rise time effects in perpendicular recording are studied using a write driver with a variable rise time. The basic recording requirement that the write current steady state should be reached before the next transition can be written is

In magnetic data storage the noise and signal-to-noise ratio (SNR) of the read heads is becoming more and more of a limiting factor given the smaller readout devices needed to follow the ever higher areal densities. For higher data rates this problem

A novel spin-stand method for measuring the perpendicular write pole "footprint" is proposed. This method allows the detailed study of the spatio-temporal pole footprint dynamics and the two-dimensional media saturation and noise. Experimental footpr

Thermal magnetic fluctuation noise forms the ultimate application limit of small magnetoresistive devices for magnetic data storage. The noise analysis of these devices becomes increasingly important for high-density recording. Such noise analyses by

This paper experimentally verifies that for low bias voltages /spl Lt/2 kT/q, the noise of a saturated magnetic tunnel junction (MTJ) device is caused by thermally assisted barrier crossings (thermal noise), whereas for voltages /spl Gt/2 kT/q, it st

The proper design of a disk drive's channel front-end is important to ensure data integrity and to achieve future high data rates. The front-end contains various interconnects which link the read/write (R/W) electronics with the recording heads and t
