This translates into about 5 megabytes to 140 megabytes per standard length (2,400 ft, 730 m) reel of tape. Effective density also increased as the interblock gap (inter-record gap) decreased from a nominal 3 ⁄ 4 inch (19 mm) on 7-track tape reel to a nominal 0.30 inches (7.6 mm) on a 6250 bpi [clarification needed] 9-track tape reel.

Bottom right: completed solar wafers. In electronics, a wafer (also called a slice or substrate) [ 1] is a thin slice of semiconductor, such as a crystalline silicon (c-Si, silicium), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells . The wafer serves as the substrate for microelectronic devices ...
The tape was originally 1 ⁄ 4 inch (6.35 mm) wide and anywhere from 300 to 1,500 feet (91 to 457 m) long. Data is written linearly along the length of the tape in one track [ 1 ] (mostly on pre-1980 equipment), or written "serpentine", one track at a time, the drive reversing direction at the end of the tape, and each track's data written in ...
9-track tape. 9-track tape is a format for magnetic-tape data storage, introduced with the IBM System/360 in 1964. The 1⁄2 inch (12.7 mm) wide magnetic tape media and reels have the same size as the earlier IBM 7-track format it replaced, but the new format has eight data tracks and one parity track for a total of nine parallel tracks. Data ...
Average wire transfer fees. Wire transfer fees have a wide range – from $0 to $50, depending on how and where you’re sending the money. Domestic outgoing wire transfer fees typically range ...
For Morse taper-shank drill bits, the standard continues in 1/64 inch increments up to 1¾ inch, then 1/32 inch increments up to 2¼ inch, 1/16 inch increments up to 3 inches, 1/8 inch increments up to 3¼ inches, and a single 1/4 inch increment to 3½ inches. One aspect of this method of sizing is that the size increment between drill bits ...
U-matic or 3⁄4-inch Type E Helical Scan[ 1][ 2] or SMPTE E[ 3] is an analogue recording videocassette format first shown by Sony in prototype in October 1969, and introduced to the market in September 1971. It was among the first video formats to contain the videotape inside a cassette, as opposed to the various reel-to-reel or open-reel ...
A 3.5 mm phone connector A 3.5 mm 4-conductor TRRS phone connector A 3.5 mm 5-conductor TRRRS phone connector. In the most common arrangement, consistent with the original intention of the design, the male plug is connected to a cable, and the female socket is mounted in a piece of equipment.
