Abstract:
A data output device comprising a plurality of data input/output means and a control means for allocating time slots to said data input/output means respectively for each cycle period having a predetermined time length, each of said data input/output means being adapted to read data from a non-linearly accessible recording medium and outputting said data in its own allocated time slot, characterized in that:at least one of said data input/output means has a memory means consisting of first and second banks for storing a volume of data good for a cycle period in its own allocated the time slot; andsaid control means controls said recording medium and said memory so as to read out a volume of data good for a first cycle period from said recording medium and store it in the first bank of said data input/output means in its own time slot and so as to read out a volume of data good for a second cycle period on the way of reading out said data good for said first cycle period and store it in the second bank of the data input/output means in the next its own time slot and start outputting data from the first bank after a preselected time, the switching from said first bank to said second bank taking place at a predetermined timing.
