    System limitations

    The recording system in your MiniDisc recorder is radically different from those used in cassette and DAT decks and is characterized by the limitations described below. Note, however, that these limitations are due to the inherent nature of the MD recording system itself and not to mechanical causes.

    Symptom Cause
    "TR FULL" appears even before the disc has reached the maximum recording time (60 or 74 minutes). When 254 tracks have been recorded on the disc, "TR FULL" appears regardless of the total recorded time. More than 254 tracks cannot be recorded on the disc. To continue recording, erase unnecessary tracks.
    "TR FULL" appears even before the disc has reached the maximum track number or recording time. Repeating recording and erasing may cause fragmentation and scattering of data. Although those scattered data can be read, each fragment is counted as a track. In this case, the number of tracks may reach 254 and further recording is not possible. To continue recording, erase unnecessary tracks.
    Track marks cannot be erased. When the data of a track is fragmented, the track mark of a fragment under 12 seconds long cannot be erased.
    The remaining recording time does not increase even after erasing numerous short tracks. Tracks of under 12 seconds in length are not counted and so erasing them may not lead to an increase in the recording time.
    The total recorded time and the remaining time on the disc may not total the maximum recording time (60 or 74 minutes). Recording is done in minimum units of 2 seconds each, no matter how short the material. Even if the last unit of recording is less than 2 seconds, it is counted as a unit of 2 seconds. Then 2 seconds´ space is put before recording starts again to prevent the last unit of the previous track from being erased. The contents recorded may thus be shorter than the maximum recording capacity.
    The edited tracks may exhibit sound drop out during search operations. The fragmentation of data may cause sound dropout while searching because the tracks are played in higher speed than normal playback.

    What is MD?

    How MiniDisc works
    MiniDisc (MD) comes in two types: premastered (prerecorded) and recordable (blank). Premastered MDs, recorded at music studios, can be played back almost endlessly. However, they can´t be recorded on or over like cassette tapes. To record, you must use a "recordable MD".
    Recordable MDs
    Recordable MDs, which use magneto-optical (MO) technology, can be recorded again an again. The laser inside the recorder applies heat to the MD, demagnetizing the magnetic layer of the MD. The recorder then applies a magnetic field to the layer. This magnetic field corresponds exactly to the audio signals generated by the connected source. (The north and south polarities equate to digital "1" and "0".) The demagnetized MD adopts the polarity of the magnetic field, resulting in a recorded MD.
    How the MiniDisc got so small
    The 2.5 inch MiniDisc, encased in a plastic cartridge that looks like a 3.5 inch diskette, uses a new digital audio compression technology called ATRAC (Adaptive TRansformation Acoustic Coding). To store more sound in less space, ATRAC extracts and encodes only those frequency components actually audible to the human ear.
    Premastered MDs
    Premastered MDs are recorded and played like regular CDs. A laser beam focuses on the pits in the surface of the MD and reflects the information back to the lens in the recorder. The recorder then decodes the signals and plays them back as music.
    Quick Random Access
    Like CDs, MDs offer instantaneous random access to the beginning of any music track. Premastered MDs are recorded with location addresses corresponding to each music selection. Recordable MDs are manufactured with a "User TOC Area" to contain the order of the music. The TOC system is similar to the "directory management system" of floppy disks. In other words, starting and ending addresses for all music tracks recorded on the disc are stored in this area. This lets you randomly access the beginning of any track as soon as you enter the track number (AMS), as well as label the location with a track name as you would a file on a diskette.
    Shock-Resistant Memory
    One major drawback of optical read systems is that they can skip or mute when subjected to vibration. The MD system resolves this problem by using a buffer memory that stores audio data.
