| 1. An information processor configured to transform a first file having an MP3 format, the file including a first area for
storing first data including at least one of title and album information, and a second area for storing second data including
a music time, to a second file having an XML-based format with a third area for storing the first data, comprising:
a memory;
an extension unit configured to extend an area of the second file to generate an XML extension area;
a first storage unit configured to store at least one of the title information and the album information of the first data
stored in the first area of the MP3 format in the third area of the XML-based format, and configured to store a first data
list of fringe information included in the first file;
a reconstruction unit configured to reconstruct the second data including the music time as third data to store the second
data in the second area, by first deciding whether or not the second data is stored in the first file on a basis of the first
data list of fringe information and, when the second data is present in the first data list as fringe information, reconstruct
the second data as third data; and
a second storage unit configured to store the third data reconstructed by said reconstruction unit in the XML extension area
of said extension unit,
wherein the reconstruction unit reconstructs the third data with an ID3 header.
