Document Summary
Analog - the waveform of the recorded signal resembles the waveform of the original signal (still noise and distortion, though) Transport - play, stop, forward, rewind: headstack - where the tape is being converted to magnetic energy o o o o. Base material - polyester (pvc); strength, prevents tape from breaking. Binder - holds oxide: magnetic oxide - holds signal in domains Relationship of time to the physical length of tape. Specific constant rate during recording and playback 1 second relative to length of tape; preserve pitch, rhythm, and duration of program (ips) o. Erase head - located before the record head in the tape path. Reduces the average magnetization level to zero (no sound) Record head - transform the analog signal into corresponding magnetic fields. Magnetic tape passing across the head will be altered. Playback head - opposite to record head; flux induced when recorded tape passes across head gap.
