Abstract
A system for high-speed access and recording includes a demodulator, a buffer memory, and a hard disk. During a write cycle, a content stream is stored in buffer memory and thereafter transferred to the demodulator. When the buffer memory reaches its storage capacity, its contents are transferred to the hard disk for storage. During a read cycle, contents from the hard disk are read and then stored in the buffer memory. The hard disk further includes includes a high-speed zone and a random-access zone, which are configured to operate in a high-speed mode, a random-access mode, and a buffer-cleaning mode.
