Bias tape or bias binding is a narrow strip of fabric, typically plain weave, cut on the bias. As the weave of fabric is at a 45-degree angle, the resulting fabric strip is stretchier than a strip cut on the grain. The strip also has a better drape, and conforms to curves better than fabric cut on the grain. [1]
Tape bias is the term for two techniques, AC bias and DC bias, that improve the fidelity of analogue tape recorders. DC bias is the addition of direct current to the audio signal that is being recorded. AC bias is the addition of an inaudible high-frequency signal (generally from 40 to 150 kHz) to the audio signal.

Bias The bias direction of a piece of woven fabric, usually referred to simply as "the bias", is at 45 degrees to its warp and weft threads. Every piece of woven fabric has two biases, perpendicular to each other. Non-woven fabrics such as felt or interfacing do not have a bias. bias tape Bias tape or bias binding is a narrow strip of fabric ...
An example of binding is double-fold bias tape. The binding's fold is wrapped around the raw edge of the seam allowance and is stitched, through all layers, catching underside of the binding in stitching. [7] Bound seams are often used on lightweight fabrics including silk and chiffon and on unlined garments to produce a neat finish.
Tape head. Tape head assembly from a compact cassette deck. The compact cassette uses four tracks, two for each side; visible are two heads (the silver rectangles inside the black rectangle) for playing one side of the tape at a time.
