Method of controlling mechanical mechanisms of optical storage apparatus for peak power/current reduction, and related optical storage apparatus and machine-readable medium

A method of controlling an optical storage apparatus which has a plurality of mechanical mechanisms including at least a first mechanical mechanism and a second mechanical mechanism, the method comprising:

• driving the first mechanical mechanism by applying a first control signal to the first mechanical mechanism, wherein the first mechanical mechanism is a sled motor, and the second mechanical mechanism is a spindle motor;
• and the second mechanical mechanism does not accelerate/decelerate its spindle rotation while the first mechanical mechanism is operating in response to the first control signal;
• adjusting the first control signal applied to the first mechanical mechanism when the second mechanical mechanism is requested to accelerate/decelerate its spindle rotation;
• and
• driving the second mechanical mechanism by applying a second control signal to the second mechanical mechanism while the first mechanical mechanism is operating in response to the adjusted first control signal.

An optical storage apparatus, comprising:

• a plurality of mechanical mechanisms, including at least a first mechanical mechanism and a second mechanical mechanism;
• and
• a control module, electrically connected to at least the first mechanical mechanism and the second mechanical mechanism, comprising:
• a first controller, arranged for driving the first mechanical mechanism by applying a first control signal to the first mechanical mechanism, wherein the second mechanical mechanism is inactive while the first mechanical mechanism is operating in response to the first control signal;
• and for adjusting the first control signal applied to the first mechanical mechanism when the second mechanical mechanism is requested to be active, wherein the first controller adjusts the first control signal applied to the first mechanical mechanism each time the second mechanical mechanism is requested to be active;
• and
• a second controller, arranged for driving the second mechanical mechanism by applying a second control signal to the second mechanical mechanism while the first mechanical mechanism is operating in response to the adjusted first control signal.

A machine-readable medium, storing a program code, when executed by a processor, causing the processor to perform following steps:

• driving a first mechanical mechanism of an optical storage apparatus by applying a first control signal to the first mechanical mechanism, wherein a second mechanical mechanism of the optical storage apparatus is inactive while the first mechanical mechanism is operating in response to the first control signal;
• adjusting the first control signal applied to the first mechanical mechanism when the second mechanical mechanism is requested to be active, wherein the first control signal applied to the first mechanical mechanism is adjusted each time the second mechanical mechanism is requested to be active;
• and
• driving the second mechanical mechanism by applying a second control signal to the second mechanical mechanism while the first mechanical mechanism is operating in response to the adjusted first control signal.
