AMPEX quadruplex VR-1000A, the first commercially released video tape recorder in the late 1950s; quadruplex open-reel tape is 2 inches wide The first portable VTR, the suitcase-sized 1967 AMPEX quadruplex VR-3000 1976 Hitachi portable VTR, for Sony 1" type C; the source and take-up reels are stacked for compactness. However, only one reel is ...
A metal bar above the take-up reel allowed a finished plot to be torn off and removed. The drum would then be advanced using the manual controls and the fresh paper end taped to the take-up reel. The standard pen was a ball-point , but liquid ink pens were available, and typically were used for higher quality plots intended for publication.
Unlike reel-to-reel tape recorders, the take-up reel on most wire recorders is not removable. A break in the wire is repaired by tying the ends together and trimming. When such a repair is made to an existing recording, a jump in the sound results during playback, but because of the high speed of the wire the loss of an inch due to tying and ...
If the user made any errors in doing this, the machine would malfunction and the tape could become damaged. So, another version, EIAJ-2, was released later on that used a single-reel cartridge (with the take-up reel being built into the VTR) instead of an open take up reel. Otherwise, the recording specifications were exactly the same.
The tape motion in the UNISERVO I was controlled by a single capstan connected to a synchronous motor.Supply and take-up reel motion was buffered via a complex pulley-string-spring arrangement, as the design was prior to the invention of the vacuum column buffer.
The TX-2 Tape System is the direct ancestor of LINCtape, including the use of two redundant sets of five tracks and a direct drive tape transport, but it uses a physically incompatible tape format (½-inch tape on 10-inch reels, where LINC tape and DECtape used ¾-inch tape on 4-inch reels). [6] [7]

This type is similar to a single-reel cartridge in that there is no take-up reel inside the tape drive. [citation needed] The IBM 7340 Hypertape drive, introduced in 1961, used a dual reel cassette with a 1-inch-wide (2.5 cm) tape capable of holding 2 million six-bit characters per cassette.
