A typical credit card reading process entails the sliding of a magnetic credit card strip through a magnetic read head
located in a card reader, while Samsung Pay's technology instead takes the data contained in the card's magnetic strip and wirelessly transmits it to the read head
using magnetic fields.
The ActivEdge encrypting read head
They further state that washboard can also cause tiny bumps on steel railway tracks, and even the read head
in a hard disk can sometimes hop along the surface of the disk to make a washboard pattern.

Spintronics exploits the fact that electrons have spin as well as charge, and spintronics devices already play a role as the active element in the read head
of most hard disk storage devices, but the physicists and materials scientists here discuss how such devices may be able to overcome such problems as heat dissipation and quantum size effects, which threaten to inhibit advances in microelectronics and nanoelectronics.
The read head
optically scans a uniquely coded rail to determine a carrier mechanism's position.
As the tape goes past the read head
, a special servo pick-up head reads the signal level of the servo track, and causes microscopic adjustments to the vertical position of the head assembly on the fly to keep it on track.
In hard drives, for example, the damping process is important for the write head that generates field pulses, the media that switch to record the field pulses as a magnetization pattern, and for the read head
sensors that detect the fields from the recorded pattern.
The Tristar is built with a 30mW GaAs laser and, by optimizing the instrument's read head
and the spatial characteristics of the laser beam, the unit has three times the signal-to-noise of the previous 20mW-based instruments.
IBM gave a taste of future hard disc data storage capabilities earlier this month when it demonstrated an advanced version of its GMR read head
able to read and write at realistic data rates against a drive carrying 20 Gb of data per square inch.
Pinarbasi spent five years at Hitachi GST, where he led the development of tunneling magneto-resistance (TMR) read head
processing used in hard disk drive products.
