The longest tape available for NTSC holds 60 minutes in SP mode and 180 minutes in EP mode. Since VHS-C tapes are based on the same magnetic tape as full-size tapes, they can be played back in standard VHS players using a mechanical adapter, without the need of any kind of signal conversion.
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]

Like most other videocassette systems, Video8 uses a helical-scan head drum (it having a small 40mm head) to read from and write to the magnetic tape. [13] The drum rotates at high speed (one or two rotations per picture frame—about 1800 or 3600 rpm for NTSC, and 1500 or 3000 rpm for PAL) while the tape is pulled along the drum's path.
The format is based on the same video tape as is used in VHS, and can be played back in a standard VHS VCR with an adapter. [2] An improved version named S-VHS-C was also developed. S-VHS's main competitor was Video8 ; however, both became obsolete in the marketplace by the digital video formats MiniDV and MiniDVD , which have smaller form factors.
On sites like eBay and LoveAntiques, collectible VHS tapes are valued at upwards of nearly $10,000 - depending on the rarity and condition of the tape, of course.
VHS VCRs cannot play back S-VHS recordings at all but can record onto an S-VHS tape in the basic VHS format. [22] Newer VHS VCRs, depending upon their specification, offered a feature called S-VHS quasi-playback or Super Quasi-Play Back, abbreviated to SQPB. SQPB lets basic VHS players view (but not record) S-VHS recordings, though reduced to ...
