Abstract: A slider includes an array of two or more transducer sets offset from one another in a cross-track direction. Each transducer set includes at least one writer and at least one reader. All of the transducer sets are configured to operate simultaneously to perform any combination of reading and writing on two or more tracks of a recording medium. At least one actuator is included between two the transducer sets. The actuator is configured to adjust a cross-track spacing between the two transducer sets in response to a control current.

Abstract: One or more magnetic recording disks are coupled to a spindle motor, each of the disks having opposing recording surfaces. Two or more actuators are moveable independently over at least a first recording surface of the one or more disks. A first actuator of the two or more actuators comprises a first write head and a first read head. A second actuator of the two or more actuators comprises at least a second read head and may include a second write head. A controller is coupled to the two or more actuators and configured to write data to a track on the first recording surface using the first write head, and perform a read operation on the data written to the track using the second read head. The controller is also configured to verify that the data was successfully written to the track in response to the read operation. The read operation can be performed within less than one revolution of the first recording surface after the write operation.
