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.
For example, the strongest print signal on a C-60 cassette running at 1.875 inches per second (4.76 cm/s) is about 426 Hz (605 Hz for a C-90), while an open-reel tape recorded at 7.5 inches per second (19 cm/s) would have its strongest signal at 630 Hz if the tape were a professional tape with a 1.5 mils (38 μm) base film or 852 Hz if the tape ...
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 3 dB ...
Noise, static or snow screen captured from a blank VHS tape. Noise, commonly known as static, white noise, static noise, or snow, in analog video, CRTs and television, is a random dot pixel pattern of static displayed when no transmission signal is obtained by the antenna receiver of television sets and other display devices.
JVC engineers Yuma Shiraishi and Shizuo Takano led the effort in developing the VHS tape format starting in 1971. [5] The project started off by designing guidelines for VHS, creating a matrix on a blackboard called the VHS Development Matrix. Included in the matrix was a list of objectives in building a home video recording unit. [6]
Once the tape reaches saturation point, any further increase in recording flux actually decreases output to below SOL. [16] Noise level, usually understood as bias noise (hiss) of a tape recorded with zero input signal, replayed without noise reduction, A-weighted and referred to the same level as MOL and SOL. The difference between bias noise ...
A Dolby noise-reduction system, or Dolby NR, is one of a series of noise reduction systems developed by Dolby Laboratories for use in analog audio tape recording. [1] The first was Dolby A, a professional broadband noise reduction system for recording studios that was first demonstrated in 1965, but the best-known is Dolby B (introduced in 1968), a sliding band system for the consumer market ...
In a video tape recorder, tracking is a calibration adjustment which ensures that the spinning playback head is properly aligned with the helical scan signal written onto the tape. In the case of VHS, a linear control track at the tape's lower edge holds pulses that mark the beginning of every frame of video; these are used to fine-tune the ...
