Record heads are constructed of laminated permalloy, ferrite, sendust or magnetoresistive materials. Tape heads and hard disk drive heads are today generally some form of magnetoresistive head; Optical - Optical recording heads use the principles of optics and light to impart energy on a recording medium, which accepts the energy in a readable ...
Rotating play heads, as used in video recorders, digital audio tape and other applications, are used to achieve a high relative head/tape speed while maintaining a low overall tape transport speed. One or more transducers are mounted on a rotating drum set at an angle to the tape.
The dummy head is designed to record multiple sounds at the same time enabling it to be exceptional at recording music as well as in other industries where multiple sound sources are involved. The dummy head is designed to replicate an average-sized human head and depending on the manufacturer may have a nose and mouth too.
M wrap, used in VHS and the D-1 (Sony) and D-2 (video) digital videotape formats, wraps the tape around the head drum in a pattern or in a tape path reminiscent of the letter M, around the left and right side of the head drum, 250 to 300 degrees around it where 180 to 270 degrees are active or used for recording, with two heads if 180 degrees ...
Threaded tape of an open Compact Cassette in the tape drive. The capstan is a rotating spindle used to move recording tape through the mechanism of a tape recorder.The tape is threaded between the capstan and one or more rubber-covered wheels, called pinch rollers, which press against the capstan, thus providing friction necessary for the capstan to pull the tape.
This allows use of the entire width of the tape, storing much more data per inch of tape, compared to the fixed head used in audio tape recording, which records a single track down the tape. The heads move across the tape at the high speed necessary to record the high-bandwidth video signal, but the tape moves at a slower speed through the machine.
This allows the video tape player to synchronize its scan speed and tape speed to the speed of the recording. Thus, the recorded control track defines the speed of playback (e.g. SP, LP, EP, etc.), and it is also what drives the relative counter clock that most VCRs have.
A cross-field head, sometimes referred to as X-field, is an additional recording head in a tape recorder that improves the ability to record high-frequency sounds. The concept was first introduced by Tandberg in their TB-6X 1960s, and more widely used by Akai and their US brand, Roberts.
