*1All minidiscs contain a Table of Contents (TOC) in addition to sound signals. The TOC is similar to the table of contents
in a book and contains information, such as track numbers, track length, and character information, that cannot be
rewritten.
*2In addition to the TOC, minidiscs also contain a special User's Table of Contents (UTOC) that contains track number, track
length, and character information, that can be rewritten.
Memory Backup for the MD Recorder Section
The contents of the memory are not stored on the disc if the power cord is unplugged.
If the power cord is unplugged suddenly or there is a power failure, the information on recording and editing
(normally recorded when the minidisc is ejected) may be erased or destroyed before it is recorded on the
minidisc. Once the information has disappeared, it can not be recovered.
After recording or editing, always remove the minidisc to record the recording or editing information.
