MEMORANDUM INCORPORATING FINDINGS OF FACT AND CONCLUSIONS OF LAW AND ORDER FOR A PRELIMINARY INJUNCTION

MacLAUGHLIN, District Judge.

This matter is before the Court on a motion for a preliminary injunction brought by plaintiff Minnesota Mining and Manufacturing Company (3M) to restrain defendant Kent A. Kirkevold, a former employee of 3M, from continuing his employment with defendant Verbatim Corporation (Verbatim) until a trial on the merits or until the time period specified in a covenant not to compete contained in Kirkevold’s employment agreement with 3M expires, whichever first occurs. The following memorandum constitutes the Court’s findings of fact and conclusions of law as required by Federal Rule of Civil Procedure 52(a). The Court has jurisdiction over the subject matter of this, action under 28 U.S.C. § 1332.

THE PARTIES

3M is a Delaware corporation with its principal place of business in Minnesota. The Data Recording Products Division of 3M is engaged in the manufacturing and worldwide marketing of magnetic media, which are various forms of information storage devices used in the operation of computers.

Kent A. Kirkevold is a 40 year old chemist who commenced his employment with [327]*3273M in February of 1964 and worked for 3M as a chemist or technician until November 27, 1979. Kirkevold resided in Woodbury, Minnesota, during the time he was employed at 3M, and worked principally in Minnesota. Although Kirkevold has not attained a college degree during his period of employment, he has acquired the equivalent of over three years of college credits. At the time this action was commenced, Kirke-vold was domiciled in California. After Kirkevold left his employment at 3M, he commenced working for Verbatim as a senior staff chemist on December 3, 1979.

Defendant Verbatim is a California corporation with its principal place of business in California. Verbatim is a competitor of 3M, as it is involved in the manufacturing and marketing of magnetic media. Verbatim is currently engaged in the development of a rigid disc product, and has enlisted Kirkevold’s efforts as an employee to assist in the development of this particular product.

MAGNETIC MEDIA — THE MANUFACTURING PROCESS AND THE INDUSTRY IN GENERAL

There are various categories of magnetic media products, and the various products differ in their application and packaging. The three basic categories are comprised of magnetic tape, flexible discs or diskettes, and rigid discs. Magnetic tape is normally placed in cassettes or cartridges. Flexible diskettes and rigid discs are shaped in donut form and come in various sizes — the major distinction between these two products is that the underlying substrate in the case of rigid discs is firmer than the substrate used for flexible discs.

As noted, the purpose of these products is to store information. This information is magnetically recorded and retrieved from the media by use of a “magnetic head” which determines the information by sensing the state of magnetization. This process is characterized by extremely close tolerances between the magnetic head and the tape, disc or diskette, often as close as 20 to 30 millionths of an inch.

A critical aspect of the manufacturing of magnetic media products is generally (and somewhat simplistically) accomplished by “coating” a substrate with what is known as a magnetic dispersion. In the case of a rigid disc, the substrate consists of an aluminum alloy, while magnetic tape and flexible diskettes utilize a polyester substrate. The magnetic dispersion process involves coating the substrate with a fluid mixture composed of magnetic iron oxide particles, a polymer or binder, a dispersant, curing or cross-linking agent and certain solvents. A dispersant is utilized to disperse the iron oxide particles evenly só as to avoid agglomeration of the magnetic particles. If the particles are not distributed evenly on the substrate (and therefore tend to agglomerate) the end result is poor recording performance. The curing agent or cross-linking agent is a chemical which is used to contribute to a proper bonding of the iron oxide particles to the substrate. These various components are mixed and then the substrate is coated by the fluid dispersion, which later hardens. A lubricant is used by 3M in connection with its rigid disc product in order to reduce the effect of friction between the magnetic head and the disc. Other than the dispersion, the various other stages in the manufacturing process include the measuring, cleaning and precoating of the substrate, as well as the polishing and cleaning of the finished product. Kent Kirkevold, in his capacity as a chemist for 3M, was involved primarily in the dispersion process, and was identified by Dr. Bruce Torp, the technical director of 3M’s data recording products division, as “an expert on . [the] manufacture of coated products,” and more specifically “dispersion making, the putting of magnetic particles into polymer, and the coating of those loaded polymer systems, or dispersions . onto substances.”

The magnetic media industry in general is a competitive and rapidly changing technological field. The technological advances in the magnetic media industry and in particular the magnetic dispersion process have been and in all probability will continue to be fast paced. 3M is a leader in the mag[328]*328netic media industry, as is Verbatim in the flexible diskette aspect of the industry. Verbatim, as noted, is in the process of developing a rigid disc product. Both 3M and Verbatim take extensive security measures to assure that the confidentiality of their manufacturing and other processes is not diminished. Due to these prevalent security measures, the only means at the disposal of competitors in the magnetic media industry to determine the extent of a competitor’s knowledge is through competitive analysis of products or through the study of patents. With respect to competitive analysis, it is not technologically possible to reconstruct the formulas or processes utilized in the development of a finished magnetic media product.

KIRKEVOLD’S EMPLOYMENT AT 3M

On February 24, 1964, Kent Kirkevold signed an employment agreement with 3M, and began working as a technician for 3M. As is 3M’s policy for all persons employed in a technical capacity at 3M, the employment agreement contained a covenant not to disclose confidential information and a covenant not to compete. A copy of the agreement is attached to this opinion. The pertinent provisions of the 3M-Kirkevold employment agreement1 provide as follows:

2. CONFIDENTIAL INFORMATION means information, not generally known, about 3M’s processes and products, including information relating to research, development, manufacture, purchasing, accounting, engineering, marketing, merchandising and selling.
4. CONFLICTING PRODUCT means any product or process of any person or organization other than 3M, in existence or under development, which resembles or competes with a product or process upon which I work during the last two years of my employment by 3M, or about which I acquire CONFIDENTIAL INFORMATION through my work with 3M.
