Gore Disk Drive Filtration Technologies

W. L. Gore and Associates, Inc. has been providing integrated particle filtration and adsorbent solutions for the computer industry for over 20 years. Beginning with applications in main frame computers, down through the advent of hard disk drives, Gore has delivered filtration and adsorbent products for all types of drive configurations. Gore introduced clean, high performing, expanded PTFE solutions to the industry and has continued to improve and advance the science behind filtration and adsorbent products in hard disk drives as the demand for smaller, better performing products has continued to evolve. 

As recording technology has advanced from thin film recording heads, through magnetoresistive heads, to today’s perpendicular recording heads; and as flying heights continue to be reduced, Gore has continued to evolve our product line to help protect the drive interior and improve drive reliability. Let Gore work with you and help design effective, low cost solutions for your drive’s filtration and adsorbent needs. Gore provides:

• High volume manufacturing
• Engineered multifunctional solutions
• Filtration expertise for maximized particle clean-up
• Adsorbent expertise for solutions to organic, corrosion, and moisture concerns
• Flexibility of product design and performance
• Applications assistance for implementation of filtration and adsorbent products
• Drive level performance testing to optimize part design
• Low cost solutions

Application Knowledge and Product Support for Every Step of the Way

As part of a commitment to quality, Gore offers applications engineering support, rapid prototyping and has analytical test capabilities for both adsorbent and filtration products.  In additional to standard chemical and particle filtration performance tests, Gore also has custom testing capabilities that can be designed to meet the exact needs of any application.
 

Protecting Your Drive from its Environment

Numerous studies show that within the vapor space of a disk drive various organic contaminants can generate a number of undesirable results such as:

• Increased stiction due to buildup of contaminants on the head or disk
• Potential data loss from polymerization products and entrapped particles that build up on the head or disk, which affects flying height and flying characteristics
• Corrosion caused by organic or inorganic acids

Gore offers a variety of standard and custom adsorbent and particle filtration products to address these issues.  Gore application engineers will work with you to meet the exact needs of your application.  Contact us for more information about engineering the best products for your drive application.
