VINTAGE COMPUTER ACCESSORIES | MAGNETIC TAPE DATA CARTAGE IN KARACHI

i am selling vintage and collectible rear computer data storage item during evolve period detail of 150 MB data cassettes to store data. Quarter inch cartridge tape (abbreviated QIC, commonly pronounced "quick") is a magnetic tape data storage format introduced by 3M in 1972,[1] with derivatives still in use as of 2016. QIC comes in a rugged enclosed package of aluminum and plastic that holds two tape reels driven by a single belt in direct contact with the tape. 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 it is serialized and written "serpentine" one track at a time, the drive reversing direction at the end of the tape, each track's data written in the opposite direction to its neighbor. Since the introduction of QIC, it has been widely used and many variations exist. There is a QIC trade association that publishes QIC standards which include interfaces and logical formats. To a very large extent it was the efficiency and openness of this organization which encouraged hardware and software developers to use this type of drive and media. price is negotiable, location DHA phase 6, Karachi. for details please whats-app me.
