Magnetized locations of the disk crank out modest currents while in the coil as it passes, therefore permitting it to “go through” a sector; in the same way, a small existing while in the coil will induce a neighborhood magnetic alter while in the disk, thereby “writing” to the sector. The disk rotates quickly (up to 15,000 rotations for each moment), and Therefore the R/W head can rapidly attain any sector over the disk.
