Recording onto a metal tape requires special high-flux magnetic heads and high-current amplifiers to drive them. [19] [79] Typical metal tape is characterized by remanence of 3000–3500 G and coercivity of 1100 Oe, thus its bias flux is set at 250% of Type I level.
The UNISERVO tape drive was the primary I/O device on the UNIVAC I computer. It was the first tape drive for a commercially sold computer. The UNISERVO used metal tape: a 1 ⁄ 2-inch-wide (13 mm) thin strip of nickel-plated phosphor bronze (called Vicalloy) 1200 feet long. These metal tapes and reels were very heavy with a combined weight of ...
Tyvek is a nonwoven product consisting of spun bond olefin fiber.It was first discovered in 1955 by a researcher for the DuPont textile company working in an experimental lab, who noticed a type of white fluff coming out of a pipe. [2]
The first commonly available increase in tape length resulted from a reduction in backing thickness from 1.5 to 1.0 mil (38 to 25 μm) resulting in a total thickness reduction from 42 to 35 μm (1.7 to 1.4 mils), which allowed 3,600 ft (1,100 m), 1,800 ft (550 m), and 900 ft (270 m) tapes to fit on ten-and-a-half-, seven-, and five-inch reels respectively.
The trade association that advocates for manufacturers in Washington, D.C., has tallied up the total costs of government red tape. Here is what it found: America’s regulatory burden cost ...
This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
On sites like eBay and LoveAntiques, collectible VHS tapes are valued at upwards of nearly $10,000 - depending on the rarity and condition of the tape, of course.
PTFE tape used for different sized fittings PTFE tape for natural gas. There are two US standards for determining the quality of any thread seal tape. MIL-T-27730A (an obsolete military specification still commonly used in industry in the US) requires a minimum thickness of 3.5 mils and a minimum PTFE purity of 99%. [3]
