Data reproduction apparatus.

摘要

A data reproduction apparatus comprising: a storage unit for storing element data, and the management data including index data dividing the element data into first and second data groups and channel data indicating a first-data-group reproduction order; a management data readout and save unit for reading out and saving the management data; a first-data-group-readout first direction unit for outputting a first readout direction for the first-data-group element data as per the channel data; an input manipulation unit for accepting instruction input to select a reproduction channel of the first-data-group element data; a first-data-group-readout second direction unit for outputting a second readout direction for the first-data-group element data as per the channel data; a first-data-group readout unit for reading out the element data as per either the first or second readout direction; a first-data-group reproduction unit for converting the readout element data into reproduction data; a first-data-group output unit for converting the reproduction data into output data; a second-data-group output judgment unit for judging adequacy of the second-data-group element data output after the first-data-group element data; a second-data-group readout unit for reading out the second-data-group element data upon adequacy judgment; a second-data-group reproduction unit for converting the readout element data into reproduction data; and a second-data-group output unit for converting the reproduction data into output data.
