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.

Abstract: A system for facilitating high-speed access and recording is provided. The system includes a demodulator, an buffer memory and a hard disk. During a write cycle, the demodulator is used to receive one or more content streams. The content streams received by the demodulator are first stored in the buffer memory. When the buffer memory has reached its storage capacity, its contents are then 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. Other components of the system can then access the read-out contents from the buffer memory. The amount of contents retrieved from the hard disk and stored in the buffer memory may be more than what is requested depending on the application requesting the contents. The hard disk further includes different zones. There are two types of zones, namely, high-speed zone and random-access zone.
