Method and apparatus for recording/reproducing multi-channel data

A method of simultaneously recording/reproducing multi-channel data on a recording medium, the method comprising:

• allocating a size of a continuous space on the recording medium, a size of channel buffers for recording, and a size of channel buffers for reproducing, based on recording/reproducing speed information of a channel in which recording/reproducing is required according to a request for recording/reproducing;
• if there is a channel buffer filled with data to be recorded among allocated channel buffers for recording, reading the data from the channel buffer to record the data on the allocated continuous space;
• and
• if there is an empty channel buffer among allocated channel buffers for reproducing, writing data read from the recording medium to the empty channel buffer,
• further comprising performing defection management for a remaining amount of time if recording/reproducing is performed faster than a sum of a time for processing a continuous data amount with a minimum value of a recording/reproducing bit rate of the channel in which recording/reproducing is required, and a maximum seek time between a continuous space and a different continuous space.
