However, S-VHS cassettes also contain a higher grade and coercivity of tape stock to effectively record the higher video bandwidth offered by S-VHS. At the thinnest acceptable width for playback, a VHS cassette can hold about 1,140 feet of tape (nearly four football fields), and about 4 hours of footage. Recordings were made by a spinning drum in a helical scan technique to increase tape-to-head speed and bandwidth. Videophiles were the first to theorize that since the only distinguishing feature of an S-VHS tape is a small 3 mm hole on the underside of the video cassette, it should be possible to use more common and inexpensive VHS tapes by duplicating that hole. S-VHS video cassettes are sensed and identified by the video cassette recorder via a specific internal profile within a hole in the underside of the S-VHS video cassette body. An Indiana Jones VHS tape from 1983 sold for almost 12,700 on eBay in May Credit: EBay. These have a different oxide media formulation for higher magnetic coercivity. " In order to take advantage of the enhanced capabilities of the S-VHS system, i.e., for the best recordings and playback, an S-VHS VCR requires S-VHS video tape cassettes. The Lion King Cassette VHS Tape Stylish Snapback Rubber Phone Cover for iPhone & Samsung - Gift. Increased luminance bandwidth produces a 60% improvement in (luminance) picture detail, or a horizontal resolution of 420 vertical lines per picture height – versus VHS's 240 lines. Throwing away your VHS and cassette tapes not only puts your personal information in danger, but also harms the environment.
In fact, you should avoid throwing VHS and cassette tapes into the trash when you can. Increased bandwidth is possible because of increased luminance carrier from 3.4 megahertz (MHz) to 5.4 MHz. Are VHS Tapes Recyclable Yes, VHS tapes are recyclable. " S-VHS improves luminance (luma) resolution by increasing luminance bandwidth. I don't know.įrom the theory I know that what is written on the tape is already saved and more can not be extracted, but maybe in practice it looks different. I think that maybe it would just make a bigger grain because of the higher resolution of reading the tape ? But the effect would be satisfactory for some - better than reading from this tape in the original as VHS. Have you ever thought about transferring(physically move) the VHS tape to the S-VHS cassette(or to create the right hole in the VHS cassette) and playing it in an S-VHS VCR that read the cassette, tape as S-VHS(probably) ? Maybe someone did and/or saw such action and comparison and knows what the effect is ?
