1. A multicontroller architecture for controlling the transfer of data and control signals between a host processor, via a host interface, and storage media comprising:

  • a plurality of low level controllers wherein each said low level controller, independently from any other said low level controller, controls the recording and retrieving of said data to and from said storage media;

    an interface controller connected to said host interface and each said low level controller for communicating with said host processor via said host interface, for controlling the data paths to and from said host interface and said storage media, and for generating and communicating parameters to said low level controllers for defining the operation to be performed by said low level controllers whereby thereinafter said low level controller can perform said operation independently of said interface controller; and

    wherein each of said low level controller comprises a first means for storing data received from said interface controller and from said storage media and a second means connected to said first means for controlling the flow of data between said first means, said interface controller and said storage media.
