Clearing continuous space on a disk store to allow consistent recording. This generally involves the moving of data on the disks to one area, leaving the remainder free so that recording can proceed track-to-track – without having to make random accesses. The larger the amount of data stored, the longer consolidation may take. Careful consideration must be given to large-capacity multi-user systems, such as video servers, especially when used for transmission or on-air.
The need for consolidation arises because of the store’s inability to continuously record television frames randomly at video rate. This is taken care of by Quantel’s FrameMagic. Recording can take place over small, scattered areas of the store so there is no need for consolidation.
