The possibility of working on computers never crossed Mr. Moon's mind until 1962, when he was hired by International Business Machines (IBM). He found the 'new' ferrite technology heads used to store and retrieve data fascinating. He eagerly worked with others to manufacture and apply these heads. In 1970, Mr. Moon took a bold step and joined with others who had founded a new company, National Micronetics Corporation. They were working on ways to use ferrite in devices that stored data as a permanent part of the computer's memory. In 1976, Mr. Moon joined Tandon Magnetics Corp. where a double-sided disk head was invented that could store and retrieve on both sides of a floppy disk. In 1980, Mr. Moon joined Apple to to work on the company's new 'Macintosh' disk drive (a joint venture with Japan's Sony Corp.). Eventually,as with other companies, Mr. Moon career soared. He became Apple's Vice President for peripherals engineering. Though Mr. Moon modestly says his inventions has not made major changes in the computer industry, he believes he has always been around things that have significantly changed the industry, including Jugi Tandon's two-sided disk head and Sony's 3-1/2 inch disk drive. Mr. Moon says his engineering skills helped make these historical inventions "better" and easier to manufacture.
