Electric motors are disclosed. The motors are preferably for use in an automated vehicle, although any one or more of a variety of motor uses are suitable. The motors include lift, turntable, and locomotion motors.

A disc drive includes: a disc driver that plays a safely seated optical disc; and a disc mover that moves the disc driver. The disc driver and the disc mover are configured to share information of their respective states with each other.

A disc device of the present disclosure includes a plurality of magazine units aligned in height direction of the disc device. Each of the magazine units includes a plurality of magazine holders each storing at least one magazine, a rail that is slidable in depth direction of the disc device along a side of a housing of the disc device and has higher stiffness than the magazine holders, and a box-shaped handle mounted to a front end of the rail to extend in width direction of the disc device. The plurality of magazine holders is arranged in depth direction of the disc device. The rail holds the plurality of magazine holders at one side of the magazine holder. The handle extends from the front end of the rail toward a free-end side of the magazine holders and includes a recessed engagement portion that admits a finger in depth direction of the disc device and enables the finger to engage when each of the magazine units is pulled out in depth direction of the disc device.

A method comprises creating calibration data using a first control circuitry of an apparatus, replacing the first control circuitry with a second control circuitry in the apparatus, and operating the apparatus with the second control circuitry using the calibration data. As an example, the apparatus may be a disc drive. The second control circuitry may be substantially similar to the first control circuitry such that calibration measurements using the first control circuitry are applicable to the second control circuitry. The first control circuitry may be included in a circuit board that is replaced with a second circuit board including the second control circuitry. In an exemplary embodiment, the second circuit board may include different and/or additional components relative to the first circuit board, such as integrated video inputs and/or video control circuitry.

A turntable device, comprising: a spindle and two arms. The two arms may comprise: a housing; one or more buttons; a spindle engagement portion; a stylus cartridge; a power supply; one or more wireless communication devices; a linear actuator; a motor; and a vertical solenoid. The spindle may receive a phonographic record, and the spindle engagement portion may engage with the spindle, such that the arms are entirely supported via said spindle and only the spindle.
