VHS-C is a downsized version of VHS, using the same recording method and the same tape, but in a smaller cassette. It is possible to play VHS-C tapes in a regular VHS tape recorder by using an adapter. After the introduction of S-VHS, a corresponding compact version, S-VHS-C, was released as well. Video8 is an indirect descendant of Betamax ...
S-VHS tapes can give better audio (and video) quality, because the tapes are designed to have almost twice the bandwidth of VHS at the same speed. Sound cannot be recorded on a VHS tape without recording a video signal because the video signal is used to generate the control track pulses which effectively regulate the tape speed on playback.
Tape hiss is the high frequency noise present on analogue magnetic tape recordings caused by the size of the magnetic particles used to make the tape. Effectively it is the noise floor of the recording medium. It can be reduced by the use of finer magnetic particles or by increasing the tape speed or the track width used by the recorder.
A control track is a track that runs along an outside edge of a standard analog videotape (including VHS). The control track encodes a series of pulses, each pulse corresponding to the beginning of each frame. This allows the video tape player to synchronize its scan speed and tape speed to the speed of
However, S-VHS cassettes contain a higher grade and coercivity of tape stock to effectively record the higher video bandwidth offered by S-VHS. S-VHS tapes can be used with VHS VCRs, but an S-VHS recording will not play back properly on a VHS VCR without SQPB (sound is usually reproduced correctly, but the picture quality will be poor).

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.
The mother tape had a coercivity three times that of normal VHS tape and was made by recording onto it using a special reel to reel video tape recorder called a mirror mother VTR using video from a D-2 (video), Type B videotape or Type C videotape master source tape. The video tape recorder had a sapphire blade to clean the surface of the ...
