Introduction; Features; Toc Pre; Toc After - Yamaha YPDR601 Operating Manual

1 • Introduction
The Yamaha Professional Disc Recorder (YPDR) system is composed of two
parts: the YPDR601 Disc Recorder Unit (referred to in this manual as "the main
unit", and the RC601 remote controller (referred to in this manual as "the con­
troller". The two are connected using a 5m (16ft) 50-pin cable (supplied).

1.1 Features

The YPDR system allows the recording of discs which may be replayed
on standard CD players.
Up to 99 tracks may be recorded on one disc, and up to 99 index markers
may be written within each track.
Recording of a disc need not be continuous audio data can be written
from different sources (master tapes, etc).
The operation of the YPDR system is similar to the operation of a tape-re­
corder, making disc production analogous to the assembly of a master
tape.
Audio sources may be analog or digital (either SDIF-II or AES/EBU format).
Monitoring may be carried out while recording, either of the source or off-
disc. The monitor output may be analog or digital (AES/EBU format).
Up to seven YPDR601 recorder units may be linked together and con­
trolled from one controller for parallel recording, or for disc duplication.
The YPDR system provides two recording modes, as described below:

1.2 TOC PRE

In this mode, the YPDR system writes a TOC (Table Of Contents) before any au­
dio data has been recorded. A TOC which references 99 tracks is written. All
tracks are the same length, and the length of each track may be set to 10 seconds
or 30 seconds (selectable from the controller).
If the 30 second track length is selected, the total recording time available on a
disc is 49 minutes, 30 seconds, and if the 10 second track length is selected, the
total recording time available on a single disc is 16 minutes, 30 seconds.
In this TOC PRE mode, the TOC is first recorded, and then audio recording is
carried out. The disc may be removed from the YPDR and replayed on a com­
mercial CD player. If the disc is not full, recording of further tracks may be car­
ried out on the YPDR for subsequent replay on CD players.

1.3 TOC AFTER

This mode varies from the TOC PRE mode in that TOC data is written on the
disc after all audio data has been recorded. This allows for variable track
lengths, but means that the disc cannot be played on standard CD players until
the TOC has been written. The YPDR, however, is capable of replaying audio
data from discs which do not yet have a TOC written to them. Once the TOC
has been written, no further recording of audio data which can be read by a
commercial CD player is possible.
The maximum length of audio data which can be written in the TOC AR ER
mode is 74 minutes, dependent on media.
