We do Quad tape transfer
The name “quadruplex” refers to the use of four magnetic record/reproduce heads mounted on a headwheel spinning transversely (width-wise) across the tape at a rate of 14,400 rpm for NTSC 525 lines/30fps-standard quad decks, and at 15,000 rpm for those using the PAL625 lines/25fps video standard. This method was called quadrature scanning, as opposed to the helical scan transport used by later videotape formats. The tape ran at a speed of either 7.5 or 15 in (190.5 or 381.0 mm) per second for NTSC 525/30 video recording, or 15.625 in (396.875 mm) per second for PAL 625/25 video; the audio, control, and cue tracks were recorded in a standard linear fashion near the edges of the tape. The cue track was used either as a second audio track, or for recording cue tones or time code for linear video editing.
Today, clients ask for either a compressed file like ProRes or an uncompressed file or a DVD. It all depends on the application.
A typical 4,800 ft (1,463 m) reel of 2 in (51 mm) quad tape holds approximately one hour of recorded material at 15 inches per second.
I bought my first Quad machine in 1983. It was an Ampex 1200B. Today, I have five of them.
