A magnetic transducer manufactured by deposition of magnetic and electrical materials on a base material contrasted with prior art mechanical methods. Read/write heads whose read/write element is deposited using integrated circuit techniques rather than being manually wound.

 

Thin-Film Media

See plated thin film media.

 

Track

One surface of a cylinder. A path which contains reproducible information left on a magnetic medium by recording means energized from a single channel.

 

Track Positioning

The method, both mechanical and electrical, used to position the heads over the correct cylinder in a disk drive system.

 

Track-Following Servo

A closed-loop positioner control system that continuously corrects the position of the disk drive's heads by utilizing a reference track and a feedback loop in the head positioning system. (See also closed loop.)

 

Tracks Per Inch (TPI)

A measurement of radial density. Tracks per inch of disk radius.
