Patent ID: 7821882

Claim:
A recording and reproducing apparatus comprising: a reproduction memory that stores compressed data read out on a sector basis from a recording medium containing the compressed data compression-coded on a block basis; a recording memory that records on a sector basis a desired part of the compressed data stored in the reproduction memory; a reproduction unit that decompression-decodes on a block basis the compressed data read out from the reproduction memory or the recording memory; and a recording unit that, in response to designation of the compressed data from a desired sector onward as the compressed data to be recorded in the recording memory, detects a first-encountered sector that includes the start position of the block in the compressed data from the designated sector onward after the start position of the designated sector, and records the compressed data from the detected sector onward in the recording memory, wherein in response to designation of the compressed data from a desired sector onward as the compressed data to be recorded in the recording memory, the recording unit detects the start position of the block closest to the start position of the designated sector in the compressed data from the designated sector onward, and records the compressed data from the detected position onward in the recording memory.
