Abstract:
1. An apparatus comprising: a disk including servo data and user data, the disk supported for controlled rotation; a transducer configured to read the servo data and the user data from the disk when the disk is rotating; a channel IC in communication with the transducer, the channel IC including a mode control portion and a channel port; a controller IC; and an interface including (i) a first portion that forms part of the controller IC, the first portion including a controller port in communication with the channel port, (ii) a second portion that forms part of the channel IC, and (iii) a set of electrical conductors that connects the controller port with the channel port, the interface configured to transfer the servo data from the channel port to the controller port according to a first data protocol and to transfer the user data between the channel port and the controller port according to a second data protocol, the second data protocol different from the first data protocol, the mode control portion controlling the mutually exclusive transfer of the user data and the servo data over the set of electrical conductors, at least a portion of the servo data and at least a portion of the user data transferred over at least one conductor of the set of electrical conductors.
