Mounting objects on a turntable

A method of securing an optical disc to the turntable of an optical disc drives comprising the steps of:

• retracting a ferritic hub and at least one ferritic clamp into the mounting assembly using magnetic attractive forces generated by an induced magnetic field;
• centering an optical disc substantially over the turntable central opening;
• collapsing the induced magnetic field within the mounting assembly;
• and,
• extending the ferritic hub and at least one ferritic clamp out of the mounting assembly through the turntable central opening such that at least one ferritic clamp makes contact with the optical disc and secures the optical disc to the turntable.

A method of mounting an optical disc to the turntable of an optical disc drive comprising the steps of:

• receiving an inserted optical disc;
• detecting the presence of an inserted optical disc;
• generating a disc input signal in response to the presence of an inserted optical disc;
• generating a magnetic field within the mounting assembly in response to the disc input signal, causing a ferritic hub and at least one ferritic clamp to retract into the mounting assembly;
• positioning the optical disc such that the optical disc is substantially centered about the turntable central opening;
• detecting the presence of the optical disc upon being substantially centered on the turntable central opening;
• generating a disc centered signal in response to the optical disc being substantially centered on the turntable central opening;
• collapsing the magnetic field in response to the disc centered signal, thereby eliminating the induced magnetic forces applied to the hub and at least one ferritic clamp;
• and
• generating an extending force that causes the hub and at least one of the clamps to extend out of the mounting assembly such that the clamp makes contact with the optical disc thereby mounting the optical disc to the turntable.

A non-transitory computer readable medium for storing a computer program, the computer program executed by a processor for controlling the operation of an optical disc drive comprising:

• computer code for detecting the presence of an inserted optical disc;
• computer code for generating a disc input signal in response to the presence of an inserted optical disc;
• computer code for sending the disc input signal to the electromagnet within the mounting assembly;
• computer code for detecting the presence of the inserted optical disc being substantially centered about the turntable central opening;
• computer code for generating a disc centered signal in response to the presence of the disc being substantially centered about the turntable central opening;
• and,
• computer code for sending the disc centered signal to the electromagnet within the mounting assembly.
