Abstract

A method and apparatus for reproducing a plurality of main data recorded on an insertable recording medium in the desired sequence specified as a playlist by the user. Main data is recorded on a record region of the recording medium and the user can select a playlist that is recorded in a management region of the recording medium.

Claims

1. An editing method to edit a playlist for reproducing main data in a desired reproduction sequence from a recording medium having a record region recorded with a plurality of the main data, a first management region having information to manage a recording position of the main data, and a second management region having information for managing the desired reproduction sequence of the main data, comprising:

a displaying step for displaying the information relating to the main data recorded on the record region based on the information in the first management region;

a selecting step for sequentially selecting the main data in order to register on the playlist using the displayed information according to a user operation; and

a registering step for registering the information related to the first management region related to the selected main data and the reproduction sequence of the selected main data on a related playlist, and for writing the related playlist on the second management region.

2. The editing method as claimed in claim 1 wherein said editing method comprises the further step of creating a plurality of playlists in said second management region.

3. The editing method as claimed in claim 2 wherein said editing method comprises the further steps of generating a playlist table for managing said plurality of playlists and recording said playlist table in said second management region.

4. The editing method as claimed in claim 3 wherein said playlist table is generated when said playlist table is not found in said second management region of said recording medium.

5. An editing device for editing a playlist for reproduction of data in a desired reproduction sequence from a recording medium having a record region recorded with a plurality of main data, a first management region having information to manage a recording position of the main data, and a second management region having at least a playlist for managing the reproduction sequence of the main data, comprising:

display means for displaying information related to the main data recorded in the record region based on information in the first management region;

operating means operated by a user for sequentially selecting the main data in order to register the playlist from among the displayed information;

write means for writing an edited playlist onto the second management area of the recording medium; and

control means for displaying with the display means the information related to the main data recorded on the record region based on the information in the first management region, for obtaining by the operating means the instructions for the main data selected by the user from the information displayed with the display means, for registering on a related playlist the data selected by the user with the information relating to the first management region and the reproduction sequence of the selected main data, and for recording the related playlist in the second management region of the recording medium by use of the write means.

6. The editing device as claimed in claim 5 wherein said editing device produces a plurality of playlists recorded in said second management region.

7. The editing device as claimed in claim 6 wherein said editing device further further comprises means for generating a playlist table and and for recording said playlist table in said second management region for managing the plurality of playlists.

8. The editing device as claimed in claim 7 wherein said editing device further comprises means for generating a new playlist table when said playlist was not retrieved in said second management region on said recording medium.
