A method for recording data on a video tape recorder (504) comprises: (a) Feeding incoming data into a buffer store (200), (b) Transferring a file of data from the buffer store (200) on to a stripe (1) of a video tape mounted on the video recorder (504), (c) Repeating steps (a) and (b) until a block of files has been recorded on a plurality of stripes contained in a length of tape, adjacent recorded stripes 1, 11, 21, 31 being separated from one another by unrecorded stripes 2-10 etc if the rate at which the data is fed to the store is less than be recorded, (d) Where steps (a) to (c) leave unrecorded stripes in the said length of tape, repeating steps (a) to (c) to record data on previously unrecorded stripes, and (e) Repeating steps (a) to (d) on successive lengths of tape. An apparatus for carrying out this recording and for reading the recorded data is disclosed. The method and apparatus are applicable to receiving image data from satellites. <IMAGE> |
