user-friendly Windows 2000 based interface
Tribology testing of a magnetic or magneto-optical head-disc interface, as well as of heads and discs separately, has transformed from a basic disc start-stop test into a comprehensive package, which includes park and fly stiction characterization, low-speed dragging, head seeking between user-defined disk radii, head sweeping of a disk surface in either continuous or on-off mode, load-unload dynamics, etc. As a result, it is undergoing fundamental changes from a few-sample destructive R&D and Qualifications testing into large-volume non-destructive product certification for both Quality Control and Incoming Inspection purposes.
The OLYMPUS TRIBO-CERTIFICATION SYSTEM incorporates the latest test procedures for the Tribology Certification of disc and head surfaces and their interfaces. It is based on the simultaneous precision measurements of dynamic friction and breakaway stiction forces in either tangential (for traditional drives) or radial (for ramp-load designs) direction, dynamic gram-load, high-frequency contact acoustic emission (AE), ultra-small thermal asperities (TA).
The ultra-low noise test system is capable of detecting very small thermal asperities and mapping their locations on the surfaces, which is useful for both Quality Control and Failure Analysis. Utilizing either regular data-heads for TA-testing in drive or head manufacturing or special wide-gap TAheads for testing in disc manufacturing ensures the compatibility of procedures, equipment and results between drive makers and component suppliers.
The combination of AE for detecting surface asperities or debris of order of several to hundreds microns, TA for detecting sub-micron asperities and debris, together with strain gauges for detecting irregularities on relatively-large contact areas, provides for a comprehensive testing and analysis
The Olympus Advanced HDI Reliability Test System is designed to perform highly accurate in-situ component level evaluations of the tribological performance (stiction, friction, wear and corresponding levels of acoustic emission, magnetic signal and thermal asperities) of magnetic and magneto optical disks and heads. Testing can be performed in the same conditions that the drive is specified, at either single disk or cartridge levels.
Olympus test systems are ideal for QC and production with up to eight testers per system and for R&D with four or less testers per system.
Olympus testers have the highest technology available and arethe best value on the market.
