These samples are similar to the free magnetic layer used in magnetoresistive (MR) heads in terms of thickness, magnetization, total moment, intrinsic coercivity
, and geometry.
81 mm), 10,000 ftpi (394 ftpmm) coercivity
550 oersteds (44,000 amperes/meter).
0076 cm, constructed of thin, flexible polyvinyl chloride (pvc) laminate with an aba standard, high coercivity
magnetic stripe rated 4000 oersted, capable of operating in temperatures of -50 to 160 f (-45 to 70 c),maximum weight of 0.
5[micro]m or more) compared to these dimensions combined with moderate magnetic coercivity
which yields broad written transitions due to the generation of transitions curving into the depth of the magnetic coating and the demagnetizing effect of sizeable opposing magnetic regions.
With the applied field oriented in the [1,1,1] direction relative to the principle axes of the bar, the problem is to calculate the remnant magnetization and coercivity
of the bar as a function of the bar width.
is defined as the applied magnetic field strength required to reduce the magnetic field in a previously magnetized sample back to zero.
To enable increased bit and track densities, media manufacturers, including Imation, have used increasing coercivity
and smaller size metal particulate (MP) pigment particles for every successive generation of tape products.
does not change with the filler content, and the saturation magnetization increases linearly with the filler content.
(hi-co) - also called high-energy tape - needs a greater magnetic force to encode the data, ten times that required for low coercivity
(lo-co), or low-energy, tape.
Acquisition of 2,500,000 personalized high coercivity
magnetic stripe and ID-I format, to issue European health insurance card PVC cards.
In the 1970s, disk drives used hand-wound ferrite core "Monkey Face" heads and 14-inch 300 Oersted coercivity
Ferric Oxide media.
