System for batch processing of magnetic media

A system for processing magnetic media, comprising a substrate handling module, comprising:

• a substrate carrier having a plurality of substrate support locations;
• a loader assembly configured to position a substrate on each substrate support location of the substrate carrier, wherein the loader assembly comprises a cassette station and a first robot comprising an end effector configured to engage an edge of the substrate in a cassette on the cassette station and rotate the substrate between a first orientation and a second orientation orthogonal to the first orientation;
• and
• a flipping assembly configured to retrieve the substrates from the substrate carrier, flip them over, and replace them on the substrate carrier, and wherein the flipping assembly comprises:
• a stage for positioning one or more substrate to be flipped;
• a static gripper head comprising one or more grippers;
• and
• a dynamic gripper head comprising one or more grippers, wherein the dynamic gripper head is actuated to flip the substrates simultaneously, wherein each gripper of the static gripper head and the dynamic gripper head includes a first end effector and a second end effector, wherein the first end effector has a central protrusion and the second end effector has two peripheral protrusions, wherein the central protrusion of the first end effector of a gripper of the one or more grippers of the dynamic gripper head is adapted to fit between the two peripheral protrusions of the second end effector of a corresponding gripper of the one or more grippers of the static gripper head, and the central protrusion of the first end effector of the gripper of the one or more grippers of the dynamic gripper head and the peripheral protrusions of the second end effector of the gripper of the one or more grippers of the static gripper head are configured to concurrently engage an inside edge of an annular substrate by extending the first and second end effectors substantially horizontally so the protrusions are in contact with the inside edge.
