Longitudinal slippage between the layers of tape in a tape pack when the roll is accelerated or decelerated.

Monitor bandwidth is proportional to the speed at which a monitor must be turned on and off to illuminate each pixel in a complete frame and is proportional to the total number of pixels displayed.
For example, a monitor with a resolution of 1000 X 1000 pixels which is refreshed at 60 times a second, requires a minimum theoretical bandwidth of over 45 MHz. Once overhead is considered for scanning and small spot size, the bandwidth could be as much as 100 MHz.

The first modern widescreen movie format, achieving a 2.35:1 aspect ratio through the use of a 2:1 anamorphic squeeze.

Two- or four-leafed metal blinders mounted onto lights to control brightness or direction.
Industry:Entertainment
The amount of bandwidth required by an unmodulated signal, such as video or audio. In general, the higher the quality of the signal, the greater the base bandwidth it requires.

a) A device which functions during the horizontal blanking or sync interval to fix the level of the picture signal at some predetermined reference level at the beginning of each scanning line. b) Also known as a DC-restoration circuit, or it can also refer to a switch used within the DCrestoration circuit. When used in the context of DC restoration, it is usually used as “clamping.” When used in its switch context, it is referred to as just “clamp.”

For magnetic tapes, the plastic substrate that supports the coating. The base film of most precision magnetic tape is made of polyester.

The thickness of the polyester material used for magnetic tape, varying from 0.24 mil in C120 cassette tape to 1.5 mil for audio mastering tape and instrumentation tape.

a) The process that establishes a fixed level for the picture signal at the beginning of each scanning line. b) The process whereby a video signal is referenced or “clamped” to a DC level to prevent pumping or bouncing under different picture levels. Without clamping, a dark picture would bounce if a white object appeared. Changes in APL would cause annoying pulsations in the video. Clamping is usually done at zero DC level on the breezeway of the back porch of horizontal sync. This is the most stable portion of a TV picture.
