A head which may be shifted horizontally to the disk surface and which consists of at least one electro-magnet. The head may magnetise the disk surface (write on it), read it and erase it; erasing being a write process with a regular pattern.
a device that can either access (read) data stored magnetically or save (write) data onto magnetic media.
The part of the hard disk that writes data to or reads data from a platter. It functions like a coiled wire that reacts to a changing magnetic field by producing a minute current that can be detected and amplified by the electronics of the disk drive.
The disk drive's magnetic head.
A device which uses induction to "write" a data pattern onto magnetic media; and which uses either inductance or magnetoresistance to "read" the data back. Heads come in many different shapes and forms, and are used for both contact and non-contact type recording.
That part of a floppy-or hard-disk system that reads and writes data to and from a magnetic disk.
(computer science) a tiny electromagnetic coil and metal pole used to write and read magnetic patterns on a disk
A sealed, magnetic coil device that moves across the surface of a disk either reading data from or writing data to the disk.
The recording element which writes data to the magnetic media and reads recorded data from the media.
A device that reads and writes data on a magnetic disk or tape
Element use to create and access the information stored magnetically on the platters/tape. A drive with several disk surfaces or platters will have a separate head for each data surface.
A small electro-magnet in a drive that skims above the surface of a disk or platter and reads information from, or writes data to, the disk.
Device that reads or writes data to a disk.
Soft "iron" core electromagnet used to read data from and write data onto a magnetic disk or tape.
That component of a disk drive or tape drive that reads from and writes to its respective secondary storage medium.
