1. A digital computer system comprising an input/output, a controller, a display, and a block storage, said storage comprising:

  • (a) at least a stack of rotatable magnetic discs having thereon block locations at physical intersections of concentric circular tracks and radial sectors;

    (b) at least an assemblage of transducers that are constrained by a servo for movement across faces of said discs to receive and transmit electronic signals representing records in said block locations;

    (c) relationships with said physical intersections determining physical block addresses of the block locations;

    (d) logical block addresses corresponding to said physical block addresses and having a data-type format that is capable of being processed by said controller;

    (e) said logical block addresses representing a relational database configuration of cells, which are defined at logical intersections of a sequence of rows that specify a sequence of records, and a sequence of columns that specify a sequence of attributes;

    (f) one of said columns defining a selected attribute of a selected record as a unique identifier of said selected record, said unique identifier representing the date/time instance of entry of said selected record into said database system;
