  • Method for storing and retrieving digital data to/from a tape recording medium through a digital interface
    Patent number: 7050704
    Abstract: A method for enabling a magnetic recording medium such as a digital video cassette tape of a digital video tape recorder to be used as an auxiliary storage device of a personal computer (PC) which communicates through a digital communication line is provided. A PC requests to record data, the digital video tape recorder searches for a recordable location of the tape, records data streams converted from the data of a file selected in the PC at the recordable location, and creates tape management information regarding the data streams recorded. A PC requests a file, the video tape recorder reproduces the tape management information recorded in the tape, identifies a recording location of the specified file based upon the reproduced tape management information, searches for the identified location in the tape, reproduces recorded data from the identified location, converts the reproduced data into transport streams, and transmits them to the PC.

  • Track-synchronous audio signal recording method and apparatus
    Patent number: 7009920
    Abstract: The present invention relates to method and apparatus of recording an audio signal composed of several tracks on a recording medium in a manner that the tracks can be distinguished each other in a recorded audio signal. The present track-synchronous recording method detects a no-sound interval longer than a predetermined time that is included in an input audio signal during recording the input audio signal, and records an audio signal following the detected no-sound interval with a different track number from that of recorded audio signal preceding the detected no-sound interval. Therefore, it is possible to individually distinguish tracks on a copy medium even though those not having any track information are copied thereto from an original at a time.
