 at a particular time. These features began as simple mechanical counter-based single event timers, but were later replaced by multiple event digital clock timers that afforded greater flexibility to the user. In later models the multiple timer events could be programmed through a menu interface that was displayed on the playback TV screen. This allowed multiple programs to be recorded easily, and this particular feature of the video recorder quickly became a major selling point and benefit to people working unsociable hours who usually missed many television broadcasts.

. VTRs originated as individual tape reels, serving as a replacement for motion picture film stock and making recording for television applications cheaper and quicker. VTRs are reel-to-reel devices that require hand-threading of the tape from a single supply reel, through the recording mechanism and onto a separate take-up reel. VCRs tend to be lower maintenance than reel-to-reel VTRs, since the tape path is usually fully enclosed to keep dust out of the mechanism, and the tape is almost never touched by the user except when malfunctions occur.

U-matic, with its ease of use, quickly made other consumer videotape systems obsolete in Japan and North America, where U-matic VCRs were widely used by television newsrooms, schools and businesses. But the cost— for a combination TV/VCR, or $7,069 in 2007 dollars—kept it out of most homes.

The late 1970s: mass-market success

It was not until the late 1970s, when European and Japanese companies developed more technically advanced machines with more accurate electronic timers and greater tape duration, that the VCR started to become a mass market consumer product. By 1979 there were three competing technical standards, with different, physically incompatible tape cassettes.

VHS vs. Betamax

The two major standards were Sony

The videotape format war was a period of intense competition or "format war" of incompatible models of consumer-level analog video videocassette and video cassette recorders in the late 1970s and the 1980s.- Overview :...

.

Betamax was first to market in November 1975, and was argued by many to be technically more sophisticated in recording quality, although many users did not perceive a visual difference. The first machines required an external timer, and could only record one hour. The timer was later incorporated within the machine as a standard feature.

The rival VHS format, introduced in Japan by JVC in September 1976 (and introduced in the United States in July 1977 by RCA) boasted a longer two-hour recording time with a T-120 tape, with four hours using a "long play" mode (RCA SelectaVision models, introduced in September 1977).

In 1978 the majority of consumers in the U.K. chose to rent rather than purchase this new expensive home entertainment technology. JVC introduced the HR3300 model with E-30, E-60, E-120, E-180 minute cassette tapes with up to three hours recording time, a thinner 4 hour length E240 tape soon followed.

The rental market was a contributing factor for acceptance of the VHS home system. 2 hours and 4 hours recording times were considered ideal for recording movies and sports-games. Although Sony later introduced L-500 (2 hour) and L-750 (3 hour) tapes in addition to the L-250 (1 hour) tape the consumer market had swiftly moved toward the VHS system as a preferred choice. During the 80s dual speed (long play) models of both BETA and VHS recorders were introduced allowing for much longer recording times.

Philips Video 2000

 head positioning to dynamically adjust the tape tracking. V2000 cassettes had two sides, and like the audio cassette had to be flipped over halfway through their recording time. User switchable record protect levers were used instead of the breakable lugs found on VHS/Beta cassettes. The half-inch tape used contained two parallel quarter-inch tracks, one for each side. It had a recording time of 4 hours per side, later extended to 8 hours per side on a few models. V2000 hit the market after its two rivals in early 1979. The last models produced by Philips in 1985 were felt by many to be superior machines to anything else on the market at the time but the poor reputation gained through the limited features and poor reliability of early models, and the by now dominant market share of VHS/Betamax, ensured only limited sales before the system was scrapped shortly after.

Product flaws

The video cassette recorder is known to have glitches and common bugs. The most common problem was temperature and humidity changes, if the machine (or tape) was moved from a cold to a hotter environment condensation would occur on the internal parts, such as the rotating video head drum. Most models were later equipped with a Dew warning

 indicator which was intended to prohibit operation. This device however could not detect moisture on the surface of any cold tape inserted. Users often experienced the magnetic tape to be 'chewed' or 'eaten' when ejected from the machine due to this moisture. Other causes of malfunction occurred when the rubber drive belts or rubber rollers hardened with age. Faults such as these rendered the tape unusable, and if valuable footage (such as a wedding) was involved this loss could be traumatic for users. VHS tapes recorded in LP or EP/SLP mode tend to not play back very well on other machines due to record / replay head alignment tolerances, and tapes recorded on a machine made before 1995 tend to not play well on newer machines due to slight changes in helical scanning head technology design. More recent models of domestic VCRs tend to have a shorter mechanical lifespan than older more robustly built units. Some new designs are built with cheaper and more fragile mechanical parts. Most machines no longer have control switches linked to mechanical parts, but rely on solenoid

 system. Newer VHS and S-VHS machines (and DVD recorders) are susceptible to this signal; generally, machines of other tape formats are unaffected, such as all 3 Betamax variants. VCRs designated for "professional" usage typically have an adjustable AGC system, a specific "Macrovision removing" circuit, or Time Base Corrector (TBC) and can thus copy protected tapes with or without preserving the protection. Such VCRs are usually overpriced and sold exclusively to certified professionals (linear editing using the 9-Pin Protocol

, TV stations etc.) via controlled distribution channels in order to prevent their being used by the general public (however, said professional VCRs can be purchased reasonably by consumers on the second-hand/used market, depending on the VCR's condition). Nowadays, most DVDs still have copyright protection, but certain DVDs do not have it, usually pornography and bootlegs. However, some DVDs, such as certain DVD sets, do not have the protection against VHS copying, possibly due to the VHS format no longer used as a major retail medium for home video.

Flying erase heads

The flying erase head is a feature that may be found in some high end home VCRs as well as some broadcast grade VCRs to cleanly edit the video

.

Normally, the tape is passed longitudinally through two fixed erase heads, one located just before the tape moves to the video head drum and the other right next to the audio/control head stack. Upon recording, the erase heads erases any old recording contained on the tape to prevent anything already recorded on it from interfering with what is being recorded.

However, when trying to edit footage deck to deck, portions of the old recording's video may be between the erase head and video recording heads. This results in a faint rainbow-like noise at and briefly after the point of the cut as the old video recording missed by the fixed erase head is never completely erased as the new recording is printed.

The flying erase head is so-called because an erase head is mounted on the video head drum and rotates around in the same manner as the video heads. In the record mode, the erase head is active and erases the video precisely down to the recorded video fields. The flying erase head runs over the tape and the video heads record the signal virtually instantly after the flying erase head has passed.

Since the erase head erases the old signal right before the video heads write onto the tape, there is no remnants of the old signal to cause visible distortion at and after the moment a cut is made, resulting in a clean edit. In addition, the ability of flying erase heads to erase old video off the tape right before recording new video on it allows the ability to perform insert editing, where new footage can be placed within an existing recording with clean cuts at the beginning and end of the edit.
