- noun the transfer of an electrical signal onto a moving magnetic tape or disk by means of a magnetic field generated by a magnetic head
- The utilization of a variable magnetic field to store a variable electrical signal on a magnetic storage medium such as a tape, disk, drum, or wire. For example, sound and/or images which wish to be recorded may be picked up by transducers such as microphones and/or cameras, where the audio and/or visual information is converted into an electrical signal. This signal is fed to a magnetic head, which then converts it into a magnetic signal which is recorded or stored on a suitable medium such as tape with an iron oxide coating.
