Providing Innovative Solutions For The Magnetic Recording Industry
The RIA-2008 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.
The system utilizes the Quad-Pole magnet configuration on either the BlazerX6-B Bar Tester or the QST-2002 HGA Tester, supporting multi-directional field vectors as incorporated in the extensive suite of RIA-2008 tests.
These tests include:
This list of advanced Writer analysis, such as Coil-To-Yoke coupling, has demonstrated correlation with Overwrite results from dynamic testing. As dynamic testing becomes less cost-effective the demand for a low cost static solution has become apparent. Further, due to the static nature of this new test system early analysis of writer performance in the production of HDD heads has been enabled, making the RIA-2008 an extremely valuable tool for both Bar and HGA applications.
