Abstract

Disclosed is a process to achieve low slider air bearing distortion (crown, camber, and twist) due to assembly and cleaning processes and temperature changes in the file and minimal fly height variation in the file without creep. Low modulus materials such as Ablestick XM and XP (epoxies), and Dymax 301-8-2 and Dymax 301-35-1 (urethane acrylate) are used to bond the slider to the suspension and high modulus materials such as RT 095-2 are used to hold the slider in position and prevent creep. The dual adhesive process utilizes low modulus materials to provide the low slider distortion and low crown sensitivity to temperature and the high modulus materials pin the slider in position and prevent creep and large elastic displacements.

Head Suspension Assembly with Reduced Slider Distortion

      Disclosed is a process to achieve low slider air bearing
distortion (crown, camber, and twist) due to assembly and cleaning
processes and temperature changes in the file and minimal fly height
variation in the file without creep.  Low modulus materials such as
Ablestick XM and XP (epoxies), and Dymax 301-8-2 and Dymax 301-35-1
(urethane acrylate) are used to bond the slider to the suspension and
high modulus materials such as RT 095-2 are used to hold the slider
in position and prevent creep.  The dual adhesive process utilizes
low modulus materials to provide the low slider distortion and low
crown sensitivity to temperature and the high modulus materials pin
the slider in position and prevent creep and large elastic
displacements.
