 Providing Innovative Solutions For The Magnetic Recording Industry




SANTA CLARA, CA – November 9, 2007: Integral Solutions International, ISI, the world’s leading manufacturer of Quasi-Static testers for the data storage industry, announced today that it has received multiple orders for their QST-2002-RT 12xHGA Level Quasi-Static Reliability tester from a leading disk drive manufacturer.

According to Henry Patland, President and CEO, “ISI has over 650 Quasi-static Testers (QST) installed worldwide making ISI the unquestioned leader in the QST arena.  With their patented technology to identify head instability early in the process, leading disk drive manufacturers are able to characterize advanced head designs early in the slider fab process and improve downstream yields as a result.   They have the largest quasi-static product line and largest installed base in the industry. They sustain their dominant position by continuing to invest in the research and development of new technologies and innovative products”. 

As MR Head technology transitions into TMR/PMR and TMR sensor dimensions shrink to advance Arial density, one of the biggest concerns for MR head manufacturers is the reliability of these sensors. 

 The QST-2002-RT is designed to address these concerns by analyzing MR performance utilizing ISI’s patented industry-standard High Frequency measurements under three primary applications: in a high temperature environment, in a hot/cold environment, or under ambient conditions.  With 12 channels the system is intended to be modular, for characterization of a small set of HGAs, or combined into a group of systems allowing the customer to exercise a large population of HGAs (ex. 10 systems capable in total of 120 channels).
