It was the team at Ampex, led by Charles Ginsburg, that made the breakthrough of using a spinning recording head and normal tape speeds to achieve a very high head-to-tape speed that could record and reproduce the high bandwidth signals of video.

A typical PDP-1 operating procedure was to output text to punched paper tape using the PDP-1's " high speed " ( 60 character per second ) Teletype model BRPE punch, then to hand carry the tape to a Flexowriter for offline printing.

The luminance signal is recorded in its original form ( albeit with some reduction of bandwidth ) but the PAL chrominance signal of about 4. 4 MHz is too sensitive to small changes in frequency caused by inevitable small variations in tape speed to be recorded directly ( NTSC suffers from the same problem ).

Oddly the first duplication of computer software id witnessed was a tape format that had been put into a twin high speed cassette stereo player and dubbed.

There were initially two types of channels ; byte-multiplexer channels, for connecting " slow speed " devices such as card readers and punches, line printers, and communications controllers, and selector channels for connecting high speed devices, such as disk drives, tape drives, data cells and drums.

Internally, they implement algorithms that dynamically match the tape speed level to the computer's data rate.

It is the only auto-reverse Walkman in history to use a two-motor, quartz-locked, disc drive system similar to high-end home cassette decks ( like the Nakamichi Dragon ) to ensure accurate tape speed for both sides ( only one motor operates at a time depending on the side of the tape being played ).

On some models, operators could achieve a speed of 20 words a minute, and the output ciphertext or plaintext was printed on paper tape.

Operators typed in the message to the paper tape, and then sent the message at the maximum line speed from the tape.

Another 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 ( a feature called tracking ).

The slower speeds cause a very noticeable reduction in linear ( non-hifi ) audio track quality as well, as the linear tape speed becomes much lower than what is commonly considered a satisfactory minimum for audio recording.

In some cases, budget labels such as Video Treasures ( both LP and EP ), Starmaker ( EP ), Burbank Video ( LP ), Avid Home Entertainment ( EP ), GoodTimes Entertainment ( LP ), and even Disney ( LP ) and Paramount ( EP ) commonly used a slower speed to reduce the amount of tape required as a cost-saving method.

VHS tapes have approximately 3 MHz of video bandwidth and 400 kHz of chroma bandwidth, which is achieved at a relatively low tape speed by the use of helical scan recording of a frequency modulated luminance ( black and white ) signal, with a down-converted " color under " chroma ( color ) signal recorded directly at the baseband.

The recorded frequency range was dependent on the linear tape speed.

For the VHS SP mode, which already uses a lower tape speed than the compact cassette, this resulted in a mediocre frequency response of roughly 100 Hz to 10 kHz for NTSC ; frequency response for PAL VHS with its lower standard tape speed was somewhat worse.

Some early VCRs would record audio without a control track signal, but this was of little practical use since the absence of a control track signal meant that the linear tape speed was irregular during playback.

The slow tape speed limited tape speed consistency, resulting in poor wow-and-flutter ( higher values ).

After it has reached terminal velocity, the time for the tape to travel a known distance is recorded.

Although the tape was run for over 1 hr., a steady state was not reached, and it was concluded that the reason for this was that the back pressure of the manometer was built up from the material fed from between the blocks and this was available at a very slow rate.

The first item in the operand, IOCSIXF, is used to specify the first IOCS index word for programs using tape files.

The second item in the operand, IOCSIXG, is used to specify the second IOCS index word for programs using tape files.

And she felt amply rewarded for her suffering when the evidence of Lee's quack shenanigans, gathered by the tape recorder under her friend's clothing, proved adequate in court for convicting Franklin D. Lee.

Since perforated tape at the time could record eight bits in one position, it also allowed for a parity bit for error checking if desired.

They proposed a 9-track standard for magnetic tape, and attempted to deal with some forms of punched card formats.

On the 2007 deluxe edition release, it is revealed that parts of this tape were used for the 1976 Griffith Park Planetarium launch of the original album, the 1987 remix, and various radio spots, all of which were included as bonus material.

* I / O ports: Expansion port, tape recorder connector ( 1200 baud variation on the Kansas City standard for data encoding ), aerial TV connector ( RF modulator ), composite video and RGB monitor output

The first version of Applesoft was released in 1977 only on cassette tape and lacked proper support for high-resolution graphics.

Examples of permanent applications include safety labels for power equipment, foil tape for HVAC duct work, automotive interior trim assembly, and sound / vibration damping films.

Removable adhesives are used in applications such as surface protection films, masking tapes, bookmark and note papers, price marking labels, promotional graphics materials, and for skin contact ( wound care dressings, EKG electrodes, athletic tape, analgesic and transdermal drug patches, etc .).

During 1976, Grant wrote her first song (" Mountain Man "), performed in public for the first time — at Harpeth Hall School — the all-girls school she attended, recorded a demo tape for her parents with church youth-leader Brown Bannister, then later when Bannister was dubbing a copy of the tape, Chris Christian, the owner of the recording studio, heard the demo and called Word Records.

| ATA / ATAPI-4 || ATA-4, || aka UDMA / 33 || || AT Attachment Packet Interface ( ATAPI ) ( support for CD-ROM, tape drives etc.

Unlike integrated archival and compression tools like PKZIP, WinZip, and WinRAR, the Unix tools ar, tar, cpio ( for " archiver ", " tape archiver " and " copy in / out " respectively ) act as archivers but not compressors.

Replacement grips have an adhesive backing, whereas overgrips have only a small patch of adhesive at the start of the tape and must be applied under tension ; overgrips are more convenient for players who change grips frequently, because they may be removed more rapidly without damaging the underlying material.

* Sport tape is useful for covering cuts or blisters, as well as providing support for joints that may have been strained.

For both NTSC and PAL Digital8 equipment, a standard-length 120-minute NTSC / 90-minute PAL Hi8 magnetic tape cassette will store 60 minutes of Digital8 video ( Standard Play ) or 90 minutes ( Long Play ).

This is a magnetic tape unit built to an old standard Technical Standard Order | TSO C84 as shown on the nameplate.

Standard procedure at EMI Studios at the time was to erase the original two-track session tape for singles once they had been " mixed down " to the ( usually monaural ) master tape used to press records.

" HS " is " High Speed ", " STD " is " Standard " and " LS " is " Low Speed "; where LS3 and LS5 represent 3 and 5 times the standard length of tape.

** LX: Standard ( Very basic model without air conditioning, cassette tape player, power windows, tachometer or other luxuries.

** SX: Standard ( Without air conditioning, cassette tape player, power windows, tachometer or other luxuries )

** SSX: Standard Plus ( Equipped with standard AC and cassette tape player )

Standard inputs were the Flexowriter keyboard and paper tape ( ten 6-bit characters / second ).

Standard procedure at Abbey Road Studios at the time was to erase the original two-track session tape for singles once they had been " mixed down " to the ( usually monaural ) master tape used to press records.
