ABSTRACT:
A compressed picture information recording apparatus which sequentially stores modulated compressed video signals in a memory, and reads information from the memory in such a way as to reduce the information reading speed when the remaining memory space becomes smaller than a predetermined value and to increase the information reading speed when the remaining memory space becomes greater than the predetermined value. This apparatus records the read information on a recording disk at a recording linear velocity according to the information reading speed. This structure permits compressed video signals excluding invalid data to be continuously recorded on the recording disk at a variable transfer rate according to the producing rate of the compressed video signals, thus ensuring a high recording efficiency.
