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.
The magnetic tape on VHS-C cassettes is wound on one main spool and used a gear wheel which moves the tape forward. It can also be moved by hand. It can also be moved by hand. This development hampered the sales of the Betamax system somewhat, because the Betamax cassette geometry prevented a similar development.
Scanning recording methods write short dense tracks across the width of the tape medium, not along the length. Tape heads are placed on a drum or disk which rapidly rotates while the relatively slow-moving tape passes it. [citation needed] An early method used to get a higher data rate than the prevailing linear method was transverse scan. In ...
Such as for example, hard disk drives in computers replacing cassette tape readers such as the Atari Program Recorder and the Commodore Datasette for software, [7] CDs and MiniDiscs replacing cassette tapes for audio, and DVDs replacing VHS tapes. Despite this, technological innovation continues.
When watching a film that exceeds 74 minutes (nearly 1¼ hours), the maximum video capacity of one disc, a viewer had to change the disc upon reaching halfway (unless the discs were played on a VCD changer that could hold multiple discs and play them automatically in succession), whereas a single VHS tape could hold 3.5 hours of continuous video.
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 ...
Unlike VHS tapes, CEDs (along with LaserDisc) required a disc flip (however, some LaserDisc players were able to read both sides of the disc without physically flipping the disc, achieved by moving the laser from one side of the disc to the other, but this still resulted in a pause of playback during the change) at some point during the course ...
Syquest EZ-drive (135 & 250 MB) disks were write-protected using a small metal switch on the rear of the disk at the bottom. VHS-C, Video8, Hi8, and DV videocassettes have a sliding tab on the rear edge. Iomega ditto tape cartridges had a small sliding tab on the top left hand corner on the front face of the cartridge.
