Abstract: An apparatus comprises magnetic recording disk surfaces and magnetic recording heads comprising a leading and a following head. A controller moves the heads so that the leading head, at a passive fly height, follows a first track of a first disk surface containing a passive thermal asperity (PTA), and the following head, at a passive fly height, follows a first track of a second disk surface. The PTAs on tracks of the second disk surface define virtual PTAs on corresponding tracks of the first disk surface. The controller moves the heads away from the respective first tracks and to neighboring tracks to avoid the PTA and virtual PTAs. The controller is configured to move the heads back to the respective first tracks so that a write or read operation can be performed by the leading head.

Abstract: An anti-reflection storage medium. The anti-reflection storage medium includes a storage layer and a protective overcoat disposed over the storage later. The protective overcoat has a first refractive index value that is matched to a second refractive index value of the storage layer to reduce reflection of incident light applied to the storage medium when data is written to the storage layer of the storage medium.
