Not for the technically illiterate, Jan Maes' "The MiniDisc" is based on a series of training sessions developed for Sony personnel in Europe. The book attempts to explain the technology behind MiniDisc from it's similarities to other optical formats (CD, CD-ROM, CD-MO) to it's distinctions (ATRAC compression, disc size, etc). Persons interested in what makes a MiniDisc system tick will get a lot out of this book. A glossary would have been helpful for those of us without degrees in audio engineering. Probably the only book of it's kind. Overall impression: favorable.
