Abstract
Apparatus and corresponding methods for storing video information. The apparatus includes a means for receiving video information, a means for converting the received video information into digital video information, and a means for storing the digital video information. Converting the received video information into digital video information can include converting it into an MPEG-compatible digital format. The apparatus can include an MPEG-compatible digital encoder, which can include separate audio and video MPEG encoders. The digital video information can be stored on an electromagnetically writable disk drive with an optimized MPEG file system (OMFS) configured to receive the digital video information and store the digital video information on the disk drive, where the OMFS is configured to divide the received digital video information into one or more packets, each packet having the same number of bytes as a sector on a disk in the disk drive. The OMFS can first accumulate one of the packets of digital video information in a cache memory. The OMFS, upon filling the cache memory with a completed packet of digital video information, then stores the completed packet on a single one of the sectors of the disk drive.
