Duct tape is cloth- or scrim-backed pressure-sensitive tape, often coated with polyethylene. There are a variety of constructions using different backings and adhesives, and the term "duct tape" has been genericized to refer to different cloth tapes with differing purposes. A variation is heat-resistant foil tape useful for sealing heating and cooling ducts, produced because the adhesive on standard duct tape fails and the synthetic fabric reinforcement mesh deteriorates when used on heating ducts.
An audio tape recorder, also known as a tape deck, tape player or tape machine or simply a tape recorder, is a sound recording and reproduction device that records and plays back sounds usually using magnetic tape for storage. In its present-day form, it records a fluctuating signal by moving the tape across a tape head that polarizes the magnetic domains in the tape in proportion to the audio signal. Tape-recording devices include the reel-to-reel tape deck and the cassette deck, which uses a cassette for storage.
Cellophane is a thin, transparent sheet made of regenerated cellulose. Its low permeability to air, oils, greases, bacteria, and liquid water makes it useful for food packaging. Cellophane is highly permeable to water vapour, but may be coated with nitrocellulose lacquer to prevent this.
Ampex Data Systems Corporation is an American electronics company founded in 1944 by Alexander M. Poniatoff as a spin-off of Dalmo-Victor.

Ampex operates as Ampex Data Systems Corporation, a subsidiary of Delta Information Systems, and consists of two business units. The Silicon Valley unit, known internally as Ampex Data Systems (ADS), manufactures digital data storage systems capable of functioning in harsh environments. The Colorado Springs, Colorado, unit, referred to as Ampex Intelligent Systems (AIS), serves as a laboratory and hub for the company's line of industrial control systems, cyber security products and services and its artificial intelligence/machine learning technology.
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 containing the tape is placed on a spindle or hub. The end of the tape is manually pulled from the reel, threaded through mechanical guides and over a tape head assembly, and attached by friction to the hub of the second, initially empty takeup reel. Reel-to-reel systems use tape that is 1⁄4, 1⁄2, 1, or 2 inches wide, which normally moves at 3+3⁄4, 7+1⁄2, 15 or 30 inches per second. Domestic consumer machines almost always used 1⁄4 inch (6.35 mm) or narrower tape and many offered slower speeds such as 1+7⁄8 inches per second (4.762 cm/s). All standard tape speeds are derived as a binary submultiple of 30 inches per second.
Sellotape is a British brand of transparent, cellulose-based, pressure-sensitive tape, and is the leading brand in the United Kingdom. Sellotape is generally used for joining, sealing, attaching and mending.
Richard Gurley Drew was an American inventor who worked for Johnson and Johnson, Permacel Co., and 3M in St. Paul, Minnesota, where he invented masking tape and cellophane tape.
A Post-it note is a small piece of paper with a re-adherable strip of glue on its back, made for temporarily attaching notes to documents and other surfaces. A low-tack pressure-sensitive adhesive allows the notes to be easily attached, removed and even re-posted elsewhere without leaving residue. The Post-it's signature adhesive was discovered accidentally by a scientist at 3M. Originally small yellow squares, Post-it Notes and related products are available in various colors, shapes, sizes and adhesive strengths. As of 2024, there are at least 28 documented colors of Post-it notes. 3M's Post-it has won several awards for its design and innovation.
The Digital Audio Stationary Head or DASH standard is a reel-to-reel, digital audio tape format introduced by Sony in early 1982 for high-quality multitrack studio recording and mastering, as an alternative to analog recording methods. DASH is capable of recording two channels of audio on a quarter-inch tape, and 24 or 48 tracks on 1⁄2-inch-wide (13 mm) tape on open reels of up to 14 inches. The data is recorded on the tape linearly, with a stationary recording head, as opposed to the DAT format, where data is recorded helically with a rotating head, in the same manner as a VCR. The audio data is encoded as linear PCM and boasts strong cyclic redundancy check (CRC) error correction, allowing the tape to be physically edited with a razor blade as analog tape would, e.g. by cutting and splicing, and played back with no loss of signal. In a two-track DASH recorder, the digital data is recorded onto the tape across nine data tracks: eight for the digital audio data and one for the CRC data; there is also provision for two linear analog cue tracks and one additional linear analog track dedicated to recording time code.
Permacel, a division of the Nitto Denko company, is an industrial adhesive tape manufacturing company. Headquartered in Pleasant Prairie, Wisconsin, United States, the company produces 350 kinds of tape used in a broad range of industries, including paper masking tape, reinforced strapping tape, paper packaging tape, PTFE tape, film tape, double coated tape, transfer tape, repulpable tape, thread seal, foil tape, surface protective films and vinyl tape. Permacel manufactured and sold graphic art tapes until 2004 when that part of their business was sold to Shurtape Technologies.
A tape dispenser is an object that holds a roll of tape and has a mechanism at one end to shear the tape. Dispensers vary widely based on the tape they dispense. Abundant and most common, clear tape dispensers are commonly made of plastic, and may be disposable. Other dispensers are stationary and may have sophisticated features to control tape usage and improve ergonomics.
Tartan track is a trademarked all-weather synthetic track surfacing made of polyurethane used for track and field competitions, manufactured by 3M. The original production was in 1967, and the product was later reformulated to eliminate the use of mercury.
Spencer Ferguson Silver III was an American chemist and inventor who specialized in adhesives. 3M credits him with having devised the adhesive that Arthur Fry used to create Post-it Notes.
Quantegy Inc. was a manufacturer of magnetic tape and professional external hard drives based in Opelika, Alabama. Their tape products were primarily used in analog audio and video recording studios, but they also have some use with digital data storage devices and instrumentation recorders along with some audiophile home hobbyists.
Recording Media Group International B.V., sometimes also named as Recordable Media Group International was a Dutch manufacturer of magnetic tape products based in Oosterhout. This plant was initially built by Philips in 1968, and spun off into a joint venture with DuPont, PDM which lasted until 1993. At this point, an unknown foreign investor took over the plant and named the company Magnetic Products Oosterhout B.V. In 2004, the company became known by its current name after acquiring equipment, processes, and talent from EMTEC's Munich plant. For its entire existence, the factory has produced magnetic tape for recording audio and video. Production of video and digital audio tapes were later ended and company concentrated only on production of high-quality analog magnetic tapes for both reel-to-reel and cassette recorders. Production of cassette tape stock were later ended as well.
Tape or Tapes may refer to:
Pressure-sensitive tape or pressure-sensitive adhesive tape is an adhesive tape that sticks when pressure is applied without the need for a solvent or heat for activation. It is also known in various countries as self-stick tape, sticky tape, or just adhesive tape and tape, as well as genericized trademarks, such as Sellotape, Durex (tape), Scotch tape, etc.
LePage's Inc. v. 3M, 324 F.3d 141, is a 2003 en banc decision of the United States Court of Appeals for the Third Circuit upholding a jury verdict against bundling. Bundling is the setting of the total price of a purchase of several products or services over a period from one seller at a lower level than the sum of the prices of the products or services purchased separately from several sellers over the period. Typically, one of the bundled items is available only from the seller engaging in the bundling, while the other item or items can be obtained from several sellers. The effect of the bundling is to divert purchasers who need the primary product to the bundling seller and away from other sellers of only the secondary product. For that reason, the practice may be held an antitrust violation as it was in the LePage's case, in which the Third Circuit held that 3M engaged in monopolization in violation of Sherman Act § 2 by (1) offering rebates to customers conditioned on purchases spanning six of 3M's different product lines, and (2) entering into contracts that expressly or effectively required dealing exclusively with 3M.
An endless tape cartridge is a tape cartridge or cassette that contains magnetic audio tape that can be played in an endless loop, without the need to rewind to repeat.
