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 ...
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 ...
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 ...
The two-head cross-field system also had problems. One was the need to keep the heads in proper alignment, which was tricky for the average user. Additionally, dirt on the tape of record head that lifted the tape away from the record head pushed it closer to the bias head, re-introducing the self-erasure problem.
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 ...
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.
Pressure-sensitive tape or pressure-sensitive adhesive tape (PSA tape) is an adhesive tape that sticks when pressure is applied without the need for a solvent (such as water) or heat for activation. It is also known in various countries as self-stick tape , sticky tape , or just adhesive tape and tape , as well as genericized trademarks , such ...
Magic Tape, also known as Magic Transparent Tape, is a brand within the Scotch Tape family of adhesive tapes made by 3M, sold in distinctive plaid packaging. Invented and introduced in 1961, it is the original matte finish tape. It appears frosty on the roll yet is invisible on paper. This quality makes it popular for gift-wrapping. [13]
