- QST-2002 Quasi-Static tester can quickly and accurately characterize
(G)MR heads performance in Manufacturing, R&D, and Failure
Analysis. With such options as HGA, HSA, HDA, and Tape Head tooling, Temperature
Stress (Electromigration) of up to 8 heads at a time, and ESD stress
the user can customize the system for their specific needs or utilize
a complete (G)MR test system.
is the world's
first Static Writer Analyzer that characterizes the magnetic performance
of the head's inductive writer by analyzing relative inductance while
applying combination of various I-Bias and multi-directional magnetic
fields. The measured magnetic performance of the writer shows strong
correlation to its performance in the drive.
- QST-2002HF Quasi-Static tester can characterize
(G)MR heads performance in R&D, and Failure
Analysis applications at extremely high magnetic fields.
tester uses the same core measurement capabilities as the
with Gen3 Front-end Electronics.
QST-2002-RT can stress and test in-situ up to 12 HGA's at various
user-defined temperatures and is designed to be part of a large HGA sample
population testing for HGA life prediction. The mode of operation is to apply
V/I Bias stress to the MR sensor (or additionally any combination of Bias
stress, Write stress, Magnetic Field Stress, DFH Stress, and Bias Pulsing
stress) at elevated temperatures for an extended period of time, then perform
standard QST and AC Channel measurements as metrics of performance degradation.
HGA/HSA/HDA toolings allow the user to perform HGA,HSA and HDA level QST
testing. Custom toolings have been developed for a variety of
2x HGA tooling allows the user to perform high throughput HGA
level QST testing, by testing 2 MR HGAs simultaneously.
Tape Head Tooling allows the user to perform QST testing on Tape
Heads, with up to 32 independent channels.
