Several of the links on the next page go into this topic in detail, and also cover Dolby noise-reduction systems.įor more information on tape recorders, cassettes, magnetic recording and related topics, check out the links on the next page.The UX560 is similar to our previous, now-discontinued pick, also from Sony. This movement means that the tape reproduces the sound recorded on it more faithfully. The bias moves the signal being recorded up into the "linear portion" of the tape's magnetization curve. A bias signal is a 100-kilohertz signal that is added to the audio signal. This works, but produces a lot of distortion on low-frequency sounds. The first tape recorders simply applied the raw audio signal to the electromagnet in the head. The controls on the tape deck let you match the recording bias and signal strength to the type of tape you are using so that you get the best sound possible.īias is a special signal that is applied during recording. Any tape player can play a metal tape, however. A normal tape deck cannot record onto a metal tape - the deck must have a setting for metal tapes in order to record onto them. Sound quality improves as you go from one type to the next, with metal tapes having the best sound quality. Metallic particles rather than metal-oxide particles are used in the tape. The ferric-oxide particles are mixed with chromium dioxide. Type 2 - This is "chrome" or CrO 2 tape.Type 1 - This is standard ferric-oxide tape, also referred to as "normal bias.". ![]()
