Description

  The present invention relates to a reproducing apparatus and a reproducing method suitable for searching for a desired song in a recording medium reproducing apparatus for recording / reproducing music data recorded on a plurality of compact discs on a hard disk, for example. .

  With the spread of compact discs, the number of compact discs owned by users has also increased. As the number of compact discs owned by users increases, it becomes difficult to organize these discs, and it becomes difficult to search for a disc containing a desired song from a plurality of discs. .

  In addition, among songs recorded on a plurality of discs, there is a case where a song of a specific artist or a song of the same genre is continuously played. When a compact disc is played back by an ordinary compact disc player, when trying to play back songs recorded on a plurality of discs as described above, the discs must be replaced.

  If a CD player having a changer function capable of storing a plurality of discs and selecting and playing a desired disc out of the plurality of discs is used, it is not necessary to put in and out the disc. Even if it has a function, it takes time to replace the disk. Even a CD player having a changer function has a limit on the number of discs that can be stored.

  Therefore, an audio recording / reproducing apparatus that uses a hard disk as a recording medium for music data and records / reproduces a desired song on the hard disk has been considered.

  That is, in recent years, the storage capacity of hard disks has increased dramatically, and it has become possible to record music data of a plurality of songs on the hard disk. The hard disk has a high access speed, and on the hard disk, the order of playback songs can be freely set. For this reason, when a hard disk is used as a recording medium for music data, songs recorded on a plurality of discs can be recorded, and the songs on the plurality of discs are sorted in order of title or artist. Can be organized. Also, since the hard disk has a fast access speed, the music selection time can be shortened.

  As described above, when a hard disk is used as a recording medium for music data, music data recorded on a plurality of disks can be recorded, and the music data recorded on the plurality of disks can be recorded in title order. It can be easily sorted and sorted in order of artist. However, the fact that a large amount of music data can be recorded means that it is difficult to search for desired music data unless the management of the music data is efficient and easy to understand.

  In the case of computer data, as a method for efficiently managing a large amount of data, management by a hierarchical structure has been conventionally performed well. Therefore, when recording music data on a hard disk, it is conceivable to manage the music data in a hierarchical structure. When music data is managed hierarchically, for example, it is classified by artist name as a major classification, classified by the artist's album at the level below each artist name, and further subordinate to the album at the level below it. The structure is such that it is classified by the name of the song. In this way, a desired song can be reproduced by following the artist name and album name.

  However, the memory of the user's music is ambiguous, and the song that the user wants to listen to is not necessarily determined. Accordingly, when managing music data, the conventional hierarchical management is not necessarily good. When managing data that evokes human emotions such as music data, a more natural management method that appeals to human intuition is desired, unlike when managing computer data.

  Accordingly, an object of the present invention is to provide a playback apparatus and a playback method capable of more intuitively managing a desired song on a desired disk when, for example, music data recorded on a plurality of disks is recorded on a hard disk. Is to provide.
