Hard disk drive having contact write and recessed magnetoresistive read head

摘要: A hard disk drive has a head with read element adjacent to write element, the extending closer than so that is proximate for writing sharp patterns and removed from avoid wear thermal asperities. The encompassed diamond-like carbon (DLC) allow at least occasional dynamic contact while which includes magnetoresistive material, disposed in recessed area may be covered thin coating of DLC avert corrosion. have multilayer granular media low-noise, high-strength perpendicular data storage. Perpendicular storage also provided by keeping such close proximity fields predominate, signals are favored element.
