Abstract:
A disk-based storage system for storing a plurality of data segments and for responding to a direction-selection signal by autonomously providing the data segments in a selected sequence so as to be concatenated together to define a continuous data stream, the disk-based storage system comprising:nonvolatile storage means including rotating disk media having a plurality of addressable locations, each of the data segments being stored in a respective one of the addressable locations, each of the addressable locations having a leading end and a trailing end, a first one of the addressable locations having a trailing end on a first track, a second one of the addressable locations having a leading end on a second track, the second track being spaced from the first track; the non-volatile storage means including means locally storing a doubly-linked list of pointers; accessing means controllable to seek to, and access, any of the addressable locations starting at the leading end and continuing through the trailing end; controller means for causing the accessing means to read the data segments in accordance with a sequence determined by the doubly-linked list of pointers and the direction-selection signal, the controller means including autonomously-operating control means responsive to the trailing end of the first one of the locations having been read for causing the accessing means to seek to the second track.
