The British-made Elliott 405 stored information on magnetic film. The council reported savings of 20% because they made people redundant.

Data loss reasons of damaged sd card: sd card says raw, says i need to format it, says not initialized; sd card suddenly not recognized; sd card damaged by power fail or Device malfunction;sd card became raw or unformatted or unallocated, unknown partition,unpartitioned;SD card file system damaged;Due to the extremely close spacing between the heads and the sd card surface, sd cards are vulnerable to being damaged by a head crasha failure of the sd card in which the head scrapes across the platter surface, often grinding away the thin magnetic film and causing data loss.
A 2 [micro]m thick CoZrTa magnetic film inductor with relative permeability ([[mu].sub.r]) of about 1000 showed a high L density of 1.3 [mu]H/[mm.sup.2] and a 28 times increase in L compared to that of the air-core inductor [2].
A team carefully pointed the tip of a scanning tunneling microscope, which can manipulate surfaces at atomic scales, toward a thin magnetic film. The tip applied a small current that twisted atoms on the film into a skyrmion (illustrated, left); reapplying the current erased the nanometer-sized vortex.
Nick Dowding, business development manager at Barden UK, said: "Hard drive disks are coated with a very thin magnetic film. The ellipsometer checks the integrity and consistency of this coating.
The technology's sensitivity limitations stem from the fact that the degree of change in resistance in an MR head's magnetic film is itself limited.
Also, to ensure that the magnetic film is a monodomain in the saturated state, the SRMs have to be specified with high squareness ([m.sub.r]/[m.sub.s] [approximately equal to] 1).
of Kennett Square, Pa., claims that it has invented a cheaper way of detecting strain by depositing a magnetic film around a thin copper wire, and says its invention could lead to many opportunities to measure strain data from parts in service inexpensively.
MO storage material is a thin magnetic film (similar to magnetic disks).
After depositing a single Zn layer on the magnetic film and annealing the sample at high temperature, the saturated magnetization significantly increased to 1.62 emu/cc.
Damon and Eshbach [140] first calculated the dispersion of dipolar modes for a thin magnetic film. They found two kinds of solutions: the surface or Damon-Eshbach (DE) and the volume mode.
