The Olympus Advanced 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 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 are the best value on the market.

Typical tests performed on Olympus testers are:

  1. Basic Start-Stop Test on the Disk Landing Zone
  2. Start-Stop Test with Periodic Head Seeking
  3. Continuous-Seeking Test
  4. Continuous-Dwell-Flying Test
  5. Park-Stiction Test
  6. Fly-Stiction Test
  7. Dynamic Load-Unload Test
  8. Load-Unload Tests at Different Disk Speeds
  9. Combination of the Load-Unload and Seeking Test
  10. Simultaneous Measurement of the Dynamic Gram-Load and Friction Force
  11. Magnetic Signal Degradation during Start-Stop Test


Small Footprint
The small footprint allows users to better utilize the available space in environmental chambers and clean-room benches
Flexible Hardware
Designed to simulate the geometry of most disk drives with form factors 5.25", 3.5", 3.0", 2.5", 1.8", and 1.0". Provides user controlled spindle speeds (up to 20,000 RPM), acceleration and deceleration with back-cogging simulation, in both CW and CCW directions, as well as any pre-defined non-linear acceleration profile simulation. Capable to start and stop at any defined radius and sector on the disk.  Allows for use of both up and down heads. Simple head mounting and loading. Z-height set with an integrated micrometer.
Precision Friction Gauge
The proprietary friction gauge allows for precise measurements of stiction and dynamic friction. The instrument is stable and linear from 5o to 70 o C and from 0% to 95% relative humidity.
Seeking Capability
The high performance servo allows for precise high-speed sweeping and seeking during test cycles. Capability to return to the same radius. Seek and sweep can be set as random or pre-defined.
Low-Distortion Chuck
Original spindle chuck ensures minimal distortion of tested disks.Microsoft Windows Interface
For ease of use, all configuration, control, and data presentation are done via a user-friendly Windows?/sup> 95 or Windows ?/sup> 2000 interface. Data Acquisition System
Complete data acquisition system allows for simultaneous real-time measurements and data analysis of friction, vertical load, acoustic emission, spindle velocity, magnetic signal amplitude and thermal asperities.
Data Management  Software allows for fast data processing in a convenient presentation format. LAN and Internet compatible.
