    Abstract: A data storage device may be configured with at least a heat assisted magnetic recording head that has a laser and is connected to a controller. The heat assisted magnetic recording head can be positioned proximal first and second data bits stored on an adjacent data storage medium. A first laser power may be applied by the laser in response to the first data bit being a different magnetic polarity than the second data bit and a different second laser power can be applied by the laser in response to the first and second data bits having a common magnetic polarity.

    Abstract: An apparatus includes a plurality of magnetic read/write heads, a system controller and a switching network. Each of the magnetic read/write heads includes a read sensor element configured to perform a read operation and a write element configured to perform a write operation. The switching network is coupled between the plurality of magnetic read/write heads and the controller. Further, the switching network is configured to substantially simultaneously select elements from at least two of the plurality of magnetic read/write heads in response to a command from the controller such that the operations of the selected elements are performed substantially simultaneously to establish a manufacturing parameter of a disk drive.
