[QuadList] Quad Carts--Links to RCA and Ampex photo examples

[Glenn Gundlach]

I don't have the specs on the ACR cart capacity but it was certainly not 20 minutes even at 7.5 IPS As I recall it was 6 minutes of actual program time at 15 IPS as there was  a bit of leader / trailer. I used to use 6 minute carts to make "poor man's test tapes" for daily use on the VR-2000s. No not the carts on the VRs, wind them back on plastic spot reels.

The Ampex carts for the ACR-25 were quite a bit larger than the RCA carts for the TCR-100.  The Ampex carts would hold about 20 minutes of tape and the RCA carts were maxed out at 3 minutes. The pictures on this website showing the carts side-by-side are not to the same scale. As for the RCA carts being difficult to open, that would only be true for someone not familiar with them.  Press the red buttons on either side and the spring loaded doors fly open.  Also, it is not likely that anyone ever recorded carts on reel to reel machines, then loaded the tape into the cassettes.  The RCA carts in particular had metal tape on the recording tape to locate the ends of of tape, and there would have been no means of adding the BOM and EOM cue tones to the tape, etc.  Both the Ampex and RCA machines had the ability to record directly to the cart.  The RCA even had a hair raising editor that could be used by the venturesome
