Soft Particle-Induced Magnetic Erasure Without Physical Damage to the Media

摘要: With ever increasing areal density, interactions of particles with a head-disk interface become an more important factor impacting the drive reliability. Although trapped between head and disk could induce mechanical damage to media resulting in permanent loss data, data has also been observed without any obvious signs physical media. We devised component-level test study this mode erasure on both glass aluminium Our indicate that frictional heating associated contact force particle lead data. In addition, we performed investigations impact air bearing design features, load/unload mechanism, number density interface.
