A video tape recorder (VTR) is a tape recorder designed to record and playback video and audio material from magnetic tape. The early VTRs were open-reel devices that record on individual reels of 2-inch-wide (5.08 cm) tape.
IVC 9000 (NTSC and PAL unit, could record for 2 hours on one 10.5 inch reel) IVC 9000-4 (4 ips tape speed, Long Play, could record and play back 4 hours on one 10.5 inch reel; IVC 9000-W (8 MHz record and playback for super bandwidth) IVC 9000-M (could record and playback video in the 655-line/48 field per second (24 frame/s) video standard)
VHS-C is a downsized version of VHS, using the same recording method and the same tape, but in a smaller cassette. It is possible to play VHS-C tapes in a regular VHS tape recorder by using an adapter. After the introduction of S-VHS, a corresponding compact version, S-VHS-C, was released as well. Video8 is an indirect descendant of Betamax ...
This is referred to as helical scan recording. A tape speed of 1 + 5 ⁄ 16 inches per second corresponds to the heads on the drum moving across the tape at (a writing speed of) 4.86 [50] [40] or 6.096 meters per second. [51] To maximize the use of the tape, the video tracks are recorded very close together.
The 1/4 inch Akai is a portable helical scan EIA and CCIR analog recording video tape recorder with two video record heads on the scanning drum. The units were available with an optional RF modulator to play back through a TV set, as well as a detachable video monitor. The Akai Electric Ltd. VTR plant was in Tokyo, Japan.
This allows the video tape player to synchronize its scan speed and tape speed to the speed of the recording. Thus, the recorded control track defines the speed of playback (e.g. SP, LP, EP, etc.), and it is also what drives the relative counter clock that most VCRs have.
In the case of VHS, a linear control track at the tape's lower edge holds pulses that mark the beginning of every frame of video; these are used to fine-tune the tape speed during playback and to get the rotating heads exactly on their helical tracks rather than having them end up somewhere between two adjacent tracks. However, the exact ...
A reel-to-reel tape recorder (Sony TC-630), typical of a 1970s audiophile device. Reel-to-reel audio tape recording, also called open-reel recording, is magnetic tape audio recording in which the recording tape is spooled between reels. To prepare for use, the supply reel (or feed reel) containing the tape is placed on a spindle or hub.
