In magnetic tape recording, adaptive biasing is the technique of continuously varying the bias current to a recording head in accordance with the level of high-frequency audio signals. With adaptive biasing, high levels of high-frequency audio signals cause a proportionate decrease in bias current using either feedforward or preferably a ...
Many lengths of bias-cut fabric can be pieced together into a long "tape", which is typically sold in metre or roll lengths by haberdashers. Bias tape varies in width from extremely narrow (1 ⁄ 4 in [0.6 cm] wide when flat) to extremely wide (as wide as 3 in [7.6 cm] or more). Bias tape is used in making piping, binding seams, finishing raw ...
A conventional tape recorder uses two heads. The main head is used for both playback and recording. A second head, placed before the main head in terms of the direction of tape movement, is used during recording to erase any previous signal. Additionally, the record head is used to introduce a tape bias signal that improves frequency response.
From the end user viewpoint, the IEC 60094 defined two principal properties of each tape type: Bias level for each type was set equal to the optimal bias of the relevant IEC reference tape, and sometimes changed when the IEC changed the reference tapes, though the BASF datasheet for the Y348M tape, approved as the IEC Type I reference in 1994 ...
A tape head is a type of transducer used in tape recorders to convert electrical signals to magnetic fluctuations and vice versa.They can also be used to read credit/debit/gift cards because the strip of magnetic tape on the back of a credit card stores data the same way that other magnetic tapes do.

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. Most contemporary tape ...
Traditional Indian charpai. At the near end, the lacing for re-tensioning the bias weave. One of many charpai patterns. Charpai (also, Charpaya, Charpoy, Khat, Khatla, Manja, or Manji) [1] is a traditional woven bed used across South Asia. The name charpai is a compound of char "four" and pay "footed".
