Abstract
A device includes a servo controller that includes or that is coupled to memory. The memory stores multiple distinct disturbance control schemes. The servo controller is configured to select and implement one of the disturbance control schemes in response to receiving a command from a host. The servo controller can be implemented on a system on a chip.
Claims20
A device comprising:
- a servo controller including or coupled to memory, which stores multiple distinct disturbance control schemes,
- wherein the servo controller is configured to select and implement one of the disturbance control schemes in response to receiving a command from a host.
A system on a chip (SOC) comprising:
- a servo controller including a servo microprocessor and memory,
- the memory storing multiple distinct disturbance control schemes,
- the servo microprocessor configured to select and implement one of the disturbance control schemes in response to receiving a command from a host.
A method for selecting disturbance control schemes stored in a memory and catalogued by index number in a library associating each disturbance control scheme with one or more product models, the method comprising:
- receiving, by a controller in communication with the memory, a command including a command index number indicative of a host product model;
- comparing the command index number to the index numbers in the library;
- selecting the disturbance control scheme associated with the index number in the library that matches the command index number;
- and
- operating a data storage device while applying the selected disturbance control scheme.
