Patent ID: 6973535

Claim:
In a system including an electromechanical digital data storage arrangement having a rotatable disk and an actuator arm for performing write operations to and read operations from said disk under the control of a servo electronics device having a servo serial interface, in cooperation with a read/write electronics device having a read/write serial interface for control thereof, and a preamp electronics device having a preamp serial interface for control thereof, such that digital data can be written to or read from said disk responsive to a host device, said storage arrangement thereby including a plurality of device serial interfaces, an interface arrangement, comprising: an external serial interface, forming part of the storage arrangement, for use in externally electrically connecting the storage arrangement and for bi-directionally externally transferring a serial control-related data, for use in operating each of the servo device, the read/write device and the preamp device; a host serial interface, forming part of the host device, in data communication with the external serial interface of the storage arrangement, configured for applying a device identification on the external serial interface in a way which directly associates at least a portion of the serial control-related data with each of the device serial interfaces; and a serial router, forming part of said storage arrangement, in data communication with each of the device serial interfaces, for using said device identification to manage said serial control-related data bi-directionally between the device serial interfaces and the external serial interface.
