These children deserve a space which is engaging and instructive, where they can feel a sense of adventure, exploration and surprise! The disk drive consists of one or more platters and heads, and the control mechanism with its associated electronics. The Winchester disk file's low-cost head-slider structure made it feasible to use two heads per surface, cutting the stroke length in half. Just as the Japanese have invaded the semiconductor industry, so did they take away part of the drive . A micro Winchester is a memory storage device for personal computers that uses a 5 1/4-inch metal memory disk. So, in effect, the first floppies were used to fill another type of data storage device. It featured a smaller, lighter read/write head that was designed to ride on an air film only 18 millionths of an inch thick. IBM's 3340 Winchester disk system, introduced in 1973, was the first HDD to use a sealed head/disk assembly, which substantially improved performance and is now standard.
