ATRAC3

Short for “Adaptive Transform Acoustic Coding3”. This is an audio compression tech- nology for high-quality and high compression. It is possible to compress music data to about 1/10th the level of a CD, allowing miniaturiza- tion of storage media.

Bit rate

This expresses data volume per second, or bps units (bits per second). The higher the rate, the more information is available to reproduce the sound. Using the same encoding method (such as ATRAC3), the higher the rate, the better the sound. (As different encoding methods are use for MP3 and ATRAC3, a simple comparison is impossible.)

Check in/Check out

Transferring music data managed on a hard disc (the music server) to a “Memory Stick” or another recording medium is called “check out”. Returning checked out music data to the hard disc is called “check in”. (Music data that has been checked out can not be checked in to a PC or other equipment.)

Except for music data for special applications where supplementary conditions operate, according to SDMI basic rules, up to four copies can be made from a single music data item. (One is saved on the hard disc, and the remain- ing three can be checked out to “Memory Stick”.)

ID3 Tag

This is a method of embedding track-related information in a MP3 file. This embedded infor- mation can include the track title, the artist’s name, the album title, the music genre, the year of production, comments and other data. The contents can be freely edited using software with ID3 Tag editing functions. Although the tags are restricted to the number of characters, the information can be viewed when the track is played back.

ISO9660 format

This is the international standard for the format logic of CD-ROM folders and files. For the ISO9660 format, there are regulations for the following two levels.

Level 1:

The file name is in 8.3 format (the name con- sists of up to 8 characters, half-byte English capital letters and half-byte numerals and the “_” sign, with a file-extension of three charac- ters.)

Level 2:

The file name can have up to 31 characters (including the separation mark “.” and a file extension). Each folder contains less than 8 hierarchies.

Extended formats

Joliet:

File names can have up to 64 characters.

Romeo:

File names can have up to 128 characters.

m3u

Playlists created using the “WINAMP” software have a playlist file extension (.m3u).

MagicGate

Data recorded on a “MagicGate Memory Stick (MG Memory Stick)” is encrypted using copy- right protection technology and can be mutually authenticated with “MG Memory Stick” compati- ble equipment. A “MG Memory Stick” can only be used to record and playback when there is verification between the “MG Memory Stick” and the compatible equipment.

“MagicGate Memory Stick”

This is the name used for a “Memory Stick” that uses the “MagicGate” copyright protection tech- nology. This is an IC recording media for recording and playback of music and other data requiring copyright protection technology.
