A base plate is a portion of a housing of a hard disk drive, and includes a cast base body. The base body includes an inner surface including an inside machined surface that is machined and an inside non-machined surface that is not machined. The base body includes an outer surface including an outside machined surface that is machined and an outside non-machined surface that is not machined. The outside machined surface and the inside non-machined surface overlap in an axial direction that is a direction parallel or substantially parallel to a rotation axis of a disk of the hard disk drive.

One embodiment provides a system comprising a motor and a disc selector mechanism. The disc selector mechanism is coupled to a bottom of a guide cage and maintained in a space below the cage. The disc selector mechanism comprises a shaft, transmission components, and a slide assembly that is laterally slidable along the shaft in response to the motor driving the transmission components. The slide assembly comprises a slide coupled to the shaft, a pivot bar coupled to the slide, and pick blades pivotally coupled to the pivot bar. A linear motion of the slide assembly along the shaft drives a linear translation of the pivot bar. The linear translation drives a pick blade of the slide assembly to move towards a side of the cage and out of the space and to pivot to a raised position to contact and lift a disc upwards into a disc gripper device.

A data storage cartridge according to one embodiment comprises a housing configured to house a data storage medium, a sensor coupled to the housing, and a microcontroller coupled to the sensor. The microcontroller is configured to wirelessly communicate information about the sensor. Other embodiments relate to a data storage cartridge comprising a housing configured to house a data storage medium, a cartridge memory coupled to the housing, the cartridge memory having a wireless communications interface, and a microcontroller in physical communication with the cartridge memory. The microcontroller is configured to wirelessly communicate information retrieved from the cartridge memory. Additional embodiments relate to a data storage cartridge comprising a mechanical write protect mechanism coupled to the housing of the data storage cartridge, an actuator coupled to the mechanical write protect mechanism for selectively changing a state of the mechanical write protect mechanism, and a microcontroller configured to control the actuator.

A data recording apparatus including: a data reading device configured to read data from a first recording medium and configured to store data and first management data for managing the data by file; a data recording device configured to record data on a second recording medium; a management data producing device configured to produce second management data for managing data recorded on the second recording medium based on the first management data of the first recording medium on which the data recorded on the second recording medium has been recorded; a data determining device configured to determine data unrecorded on the second recording medium by comparing the first management data read by the data reading device from the first recording medium with the second management data recorded on the second recording medium; a control device configured to read the data determined by the data determining device from the first recording medium and cause the recording device to record the read data onto the second recording medium; and a display device configured to display the recording status of data, managed by the first management data read by the reading device from the first recording medium, on the second recording medium, wherein the recording status includes one of recording of data complete, recording of data in progress, and recording of data yet to begin.
