618 Chapter 21
DLR also allows full bit-by-bit recordings to be made of the new HDCD-encoded discs
(see earlier, this chapter). The entire encoding of these discs is therefore reproduced on
the copy and is available for playback on compatible CD players with a HDCD decoder.
Audio conversions from other analogue sources are also of high quality using the
analogue inputs provided. This makes it easy for the user to transfer LP or older disc
collections to CD, as well as to record from other analogue sources such as tapes, radio,
or even live music (given suitable microphones).
The CDR 770 also incorporates a CD text function, allowing the consumer to put in text
information such as album, artist, or track name. When you make a CD recording using
the CDR 770 you can enter your own personal text for each disc, for each track, or for
each artist. Each of these text items can contain up to 60 characters. The text is then
shown on the display during playback. CD text that is present on prerecorded discs will
also be displayed when playing the disc back in a Philips Audio CD-Recorder.
Conscious that the hi-fi user is less accustomed to setting up digital equipment than a
computer user, Philips has redesigned the user interface of the CDR 770 so as to make
the recording action easier and more intuitive. This uses clear messages at every stage to
prevent errors and shows the user exactly what to do next. For example, the new Make CD
function allows discs to be recorded and fi nalized quickly and conveniently, using a single
command rather than a set of operations in sequence. Another useful feature is multitrack
erase, allowing multiple tracks to be selected and erased at the same time. In addition, the
CDR 770 features 99-track programming, easy recording start, an FTD display that gives
a clear, at-a-glance indication of the set status, and a music calendar with track bar.
One common problem that users have with hi-fi CD recording is mistaken starts, starting
the wrong piece for recording or starting in the wrong place. Because CD-R is a medium
that does not allow erasing, this action either makes a set of tracks that you do not want
to play or makes the whole disc unusable. This is no problem for the computer user who
makes use of a CD-R/RW drive, because the digital fi les are stored and can be edited before
recording, but this is not the way that the hi-fi type of CD recording deck works. Philips has
included a buffer memory into the CDR 770, allowing storage of up to 3 s of music.
