Western Digital (first named General Digital Corporation) was founded in California in 1970. The 3.5-inch disk drive had a capacity of 16.8GB. The underlying system software, which we wrote from scratch, was interrupt driven, so we could support simultaneous I/O operations, such as keying in commands while the printer was running or typing ahead of the 10 character per second teletype. The Winchester technology allowed the head to land and take off from the disk media as the disk spun up and down. Mateosian is currently a review editor at IEEE Micro in Berkeley, CA. The entire operating system and all of the application programs were in HP 2100 series assembly language. About the time the 3340 was introduced, IBM decided to move sales of disk packs and Data Modules from its Data Products Division (mainframes) to its Information Records Before the Winchester architecture, removable disks were like removable disks today, in which the read/write heads remain in the drive and make contact with the platter after the cartridge is inserted. The IBM3340 hard disk drive (HDD) that began shipping in November 1973 pioneered new low-cost, low-load, landing read/write heads with lubricated disks, and established what became the dominant HDD technology. The RAMAC disk drive created a new level in the computer data hierarchy, today known as secondary storage, less expensive and slower than main memory (then typically core or drum) but faster and more expensive than tape drives. 1980s - The era of home computing Our editors will review what youve submitted and determine whether to revise the article.
