Abstract
Apparatus for storing and retrieving data such as in a computer network. A plurality of local data storage units each comprise a local control circuit and a housing which encloses a moveable data transducer adjacent a data storage medium. A shared resource module physically interconnects each of the local units, and includes shared circuitry that supplies a resource required by the local control circuits to transfer data to and from the data storage media. In some preferred embodiments, the resource comprises a programming instruction set that is utilized by a programmable processor in each of the local control circuits, such as servo code used to provide data transducer positional control. Alternatively, the resource comprises a shared buffer memory space utilized by read/write channels in each of the local control circuits. Preferably, data are stored across the data storage media using RAID techniques (redundant array of independent discs/devices).
