  • Patent number: 10664172
    Abstract: A data storage device includes a first system-on-a-chip (SOC) associated with a first read transducer that accesses one or more magnetic disks of the data storage drive. The first SOC has a first read channel operable to receive data from the first read transducer. A second SOC is associated with a second read transducer that accesses the one or more magnetic disks of the data storage drive independently of the first read transducer. The second SOC has a second read channel operable to receive second data from the second read transducer. The first and second SOCs are coupled via a data bus that facilitates communicating the first and second data to a host via a first host interface.

The system can also include a second camera disposed in the volume of space, where the second camera captures a second image of a second portion of the volume of space. The system can further include a controller communicably coupled to the first camera and the second camera. The controller can receive the first image from the first camera and the second image from the second camera. The controller can also generate a resulting image by combining the first image and the second image. The controller can further perform an action using the resulting image.

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.
