system, introduced in Tokyo in September 1971, was the world's first commercial videocassette format. Its cartridges, resembling larger versions of the later VHS cassettes, used 3/4-inch (1.9 cm)-wide tape and had a maximum playing time of 60 minutes, later extended to 80 minutes. Sony also introduced two machines (the VP-1100 videocassette player and the VO-1700, also called the VO-1600 video-cassette recorder) to use the new tapes. 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 (Sony BVU-150 and Trinitron DXC 1810 video camera), schools, and businesses. But the high cost – for a combination TV/VCR – kept it out of most homes.

Mass-market success
The industry boomed in the 1980s as more and more customers bought VCRs. By 1982, 10% of households in the United Kingdom owned a VCR. The figure reached 30% in 1985 and by the end of the decade well over half of British homes owned a VCR.

Flying erase head
Some high-end VCRs featured a flying erase head integrated alongside the video and Hi-Fi heads on the spinning drum. The head erases the old signal just before the new signal is recorded, enabling clean cuts and video inserts. The head is 40 microns wide, erasing both fields of video, removing the need for another head.Unlike the stationary full width erase head, the flying erase head eliminates chroma interference at the beginning of a new recording, as it erases the video almost immediately before being written to the tape.
Shortcomings
Video cassette recorders are sensitive to changes in temperature and humidity. If the machine (or tape) is moved from a hot to a colder environment, there could be condensation of moisture on the internal parts, such as the rotating video head drum. Some later models were equipped with a dew warning which would prevent operation in this case, but it could not detect moisture on the surface of a tape. The presence of moisture between the tape and the rotating head drum increases friction which prevents correct operation and can cause damage to both the recording device and the tape. In extreme cases, if the dew sensor fails to function and stop the video recorder, moisture can cause the tape to stick to the spinning video head. This can pull a large amount of tape from the cassette before the head drum stops spinning. The tape will be extensively damaged, the video heads will often become clogged, and the mechanism may be unable to eject the cassette. The dew sensor itself is mounted very close to the video head drum. Contrary to how one might expect this to behave, the sensor increases its resistance when moisture is present. Poor contacts on the sensor can therefore be a cause of random dew sensor warnings. Usually, a "DEW" indicator or error code lights up on the display of most VCRs/camcorders, and on some, a

JVC did ship one model of D-VHS deck with a built-in ATSC tuner, the HM-DT100U, but it remains extremely rare, and therefore expensive. In July 2016, Funai Electric, the last remaining manufacturer of VHS VCR/DVD combo recorders, announced it would cease production of VHS recorders by the end of the month.

format. However, with many homes still having a large supply of VHS tapes and with all Blu-ray players designed to play regular DVDs and CDs by default, some manufacturers began to make VCR/Blu-ray combo players.
Quality
Due to the path followed by the video and Hi-Fi audio heads being striped and discontinuous—unlike that of the linear audio track—head-switching is required to provide a continuous audio signal. While the video signal can easily hide the head-switching point in the invisible vertical retrace section of the signal, so that the exact switching point is not very important, the same is obviously not possible with a continuous audio signal that has no inaudible sections. Hi-Fi audio is thus dependent on a much more exact alignment of the head switching point than is required for non-HiFi VHS machines. Misalignments may lead to imperfect joining of the signal, resulting in low-pitched buzzing.
