Dysan was a storage media manufacturing corporation, formed in 1973 in San Jose, California, by CEO and former president C. Norman Dion of San Jose, California. It was instrumental in the development of the 5.25" floppy disk, which appeared in 1976.
In 1983, Dysan was a Fortune 500 company, had over 1200 employees, and was ranked as among the top ten private sector employers within the Silicon Valley by the San Jose Mercury News, in terms of number of employees. In addition, some of Dysan's administrative and disk production facilities, located within the company's Santa Clara, California, manufacturing campus, were regarded as architecturally remarkable. For example, some of Dysan's Santa Clara campus disk manufacturing facilities included architectural features such as large indoor employee lounge atriums, incorporating glass encased ceilings and walls, live indoor lush landscaping, waterfalls, running water creeks, and ponds.
In addition to manufacturing floppy and hard disks, Dysan also produced hardware and storage containers for the disks.
Norman Dion later sold Dysan to Xidex Magnetics in the spring of 1984. In 1997, under the direction of Jerry Ticerelli, the company declared bankruptcy. After a brief re-opening in 2003, the company closed six months later under the direction of Dylan Campbell.
Dysan was an environmentally friendly company before it was fashionable. It is possible they were one of the first tech-based companies to offer a service for recycling used product. Some Dysan packaging included the following label:
Flexible media should be disposed of in an environmentally sound manner. Consumers may send used diskettes (regardless of brand) to:
Unfortunately, this service was discontinued with the closure of the company.
