A variation in thickness or elasticity across the width of the tape, it may be a coating defect, or it may be caused by stretch damage either during manufacture or in use. It results in a variation of the recovered RF due to the effect on head-to-tape contact and may result in color saturation banding and velocity errors.

A hard border usually applies to patterns and is characterized by an abrupt change from background video to the border video and by an abrupt change from the border video to the foreground video. Also sometimes used to describe key borders with a high gain.
Industry:Software
a) Term used generically for equipment, i.e., VTRs, switchers, etc. b) Individual components of a circuit, both passive and active, have long been characterized as hardware in the jargon of the engineer. Today, any piece of data processing equipment is informally called hardware.

If a sine wave of a single frequency is put into a system, and harmonic content at multiples of that frequency appears at the output, there is harmonic distortion present in the system. Harmonic distortion is caused by nonlinearities in the system.
Industry:Software
a) Whole number multiples of a frequency. F x 1 is called the fundamental or first harmonic; F x 2 is the second harmonic; F x 3 is the third harmonic; etc. b) Integral multiples of a fundamental frequency are harmonics of that frequency. A pure sine wave is free of harmonics. Adding harmonics to a fundamental frequency will change its wave shape. A square wave contains a fundamental frequency plus all the odd harmonics of that frequency.

In a magnetic recorder, the generally ring-shaped electromagnet across which the tape is drawn. Depending on its function, it either erases a previous recoding, converts an electrical signal to a corresponding magnetic pattern and records it on the tape, or picks up a magnetic pattern already on the tape and converts it to an electrical playback signal. 2-Head: The system used on most cassette recorders, requiring that playback occur after the recording has been made. 3-Head: Refers to the recording/playback head configuration within the recorder. A 3-head system allows simultaneous playback of recorded material.
Industry:Software
Mechanical adjustment of the spatial relationships between the head gaps and the tape.
Industry:Software
An assembly holding an erase, record, and playback head in a certain physical alignment.
Industry:Software
A device used to neutralize possible residual or induced magnetism in heads or tape guides.
