This manual covers the two models of the MD-801
Mk II product line: the MD-801R Mk II, which is
capable of recording and playing back on MiniDisc
media, and the MD-801P Mk II, which is for playback only of such media. Apart from the recording
and associated facilities provided on the MD-801R,
the functionality and specifications of the two units
are identical. For brevity, the unit will be referred to
as the “MD-801” in instances where there is no difference between the recording and playback models.
When a section of this manual describes a function
which is included as part of the MD-801R only, the
section will be marked as below:

There are no features which are unique to the MD-
801P model.
1.1 About the MiniDisc format
Full explanations of the principles of magneto-optical recording may be found in a number of excellent
reference works, but briefly, during the recording
process, the disc is exposed to a strong laser beam
which heats the disc’s magnetic medium so that a
magnetic field can be applied to change the orientation of the magnetic particles. On cooling, this orientation is permanently fixed, unless the disc is
reheated and re-recorded.
The MD format therefore provides the convenience
and durability of an optical disc format with the reusabilty characteristics of tape.
1.1.1ATRAC compression
If a MiniDisc were to be recorded using exactly the
same techniques as a CD, the playback time would
be only 15 minutes of stereo playback.
However, using a technique known as ATRAC
(Adaptive TRansform Acoustic Coding), 74 minutes
of stereo audio at 44.1 kHz sampling frequency with
a 16-bit word length can be recorded on an MD.
This section provides some basic information regarding the MiniDisc format. If more detailed information is required, the reader is referred to one of the
many books on the subject. John Wilkinson,
of Digital Audio
an excellent reference source, particularly Chapter
12, which deals with the use of optical discs in audio
applications.
The MiniDisc format (MD) is a convenient form of
digital audio media, using optical playback, similar
to CDs.
The format of the MD is substantially smaller than
that of the CD, and the disc itself is housed in a cartridge with a shutter, similar to that of a 3.5” floppy
disc drive. The disc platter should never be removed
from this cartridge.
Pre-recorded MDs, which are manufactured in the
same way as commercial CDs, using a stamper process, are read using a laser beam to read the pits
stamped onto the disc.
Recordable MDs are also available, and the technology used for recording on a recordable MD is
magento-optical, allowing the disc to be re-used
many times. Shutters on both sides of the disc allow
access to the disc surface by the recorder’s laser and
magnetic head.
There is a third kind of MD, the hybrid, which contains pre-recorded pits at the center of the MD,
together with an area reserved for user recording.
2nd ed. Oxford: Focal Press, 1994 is
The Art
ATRAC uses two important pyscho-acoustic principles to reduce the size of the recorded data: the
greater sensitivity of the human ear to mid-range signals, relative to bass and treble signals, and the
“masking” effect, whereby quieter signals are hidden
by louder ones.
The ATRAC used in the MD-801R/P Mk II is a very
recent version of this encoding scheme (4.5), resulting in an almost inaudible loss of signal quality.
1.1.2Buffer memory
The ATRAC compression scheme has an additional
advantage, as a RAM buf fer must be provided for the
compressed data, before it is decoded and sent to the
D/A converters.
On the MD-801R/P Mk II, this buffer memory holds
about 10 seconds’ worth of data. The advantage is
that, unlike a CD player, the MD-801R/P Mk II is not
vulnerable to mechanical shocks and vibration, etc.,
which can cause a CD player playback pickup to
jump and cause audible skipping.
1.1.3Random access and U-TOC
The format of a recordable MD is much closer to that
of a computer disc than of conventional audio media.
The random access nature of the disc media allows a
logical “track” to be composed of sections of audio
data recorded at different points on the disc.
In the same way that a computer’s operating system
hides the details of the way that data is stored on the
TASCAM MD-801R/P Mk II
1–1
1 - Care of MD media
disk from the user, and a file appears as one contiguous block of data (even though it may be spread ov er
many tracks and sectors of the disk), the MD player
allows separated audio data to appear as a continuous
audio track.
The MD-801 allows the creation and reading of a
User Table of Contents (U-TOC) on recordable
discs, which contain instructions to the player on the
logical arrangement of the tracks, where to find the
next audio segment to be played, etc. This is similar
to the directory tracks provided as part of a computer
disk operating system.
The random access facilities provided by the MD801 are significantly better than those to be found on
consumer MD decks. The effective start time can be
effectively zero, compared with hundreds of milliseconds on consumer units.
1.1.4Track titling, etc.
In common with other forms of digital audio media,
the MD medium allows other data to be recorded
alongside the audio data. In the MD medium, this is
used to provide alphanumeric disc and track titles,
which are shown on the display of the player.
In the case of the MD-801R/P Mk II, this information
may be conveniently entered through a standard
computer keyboard (PS/2 compatible), or through the
controls of the main unit.
In addition, a realtime clock allows date- and timestamping of tracks recorded on the unit or created or
edited through TOC editing functions.
These times will be displayed when the disc is
replayed on any one of the MD-801 series.
1.2 Care of MD media
The MD medium has been designed to be robust, and
the integration of the disc into a cartridge protects the
recorded surface from the worst effects of dust, fingerprints, and scratches.
Even so, there are some commonsense precautions
that you should take when storing and handling
MiniDiscs.
• Do not open the shutter and touch the surface of the
disc.
• Do not keep MiniDiscs in excessively dusty locations, in direct sunlight, in areas subject to high
temperatures, or high levels of humidity.
• If the cartridge becomes dirty, clean it with a dry,
soft cloth. Do not use any solvents or other liquids.
1.3 About the MD-801R/P Mk II

1.3.1Unpacking the unit
When you unpack the unit, as well as the unit itself
and this manual, you should find:
1.3.2Rack-mounting the unit
The MD-801 is equipped with integral rack-mount
ears, and may be installed in any standard vertical
19” rack.
Remove the feet from the MD-801 using a Phillips
screwdriver before installing the unit.
In addition to the 3U of space required for the MD801 itself, we strongly suggest leaving at least 1U of
empty rack space above the MD-801 for ventilation
purposes.
1.3.3Care of the unit
The commonsense precautions that you should take
with any piece of precision electronic equipment also
apply to the MD-801. In particular:
• Do not subject the unit to severe shocks or vibration. Despite the buffer mechanism mentioned
above, there is a risk of data loss, particularly while
recording.
• Do not use the unit in very dusty or smoky en vironments. If the optical lens or the head becomes dirty
as the result of such use, use a commercially-available MD lens and head cleaner to clean the lens.
• The exterior of the unit may be cleaned with a soft
dry cloth, or a cloth barely dampened with a mild
detergent solution. Do not use any solvent, thinner
or alcohol-based cleaning agents to clean the unit.
The date and time clock (for timestamping of recordings and edits) is powered by a lithium battery. We
suggest that this battery is changed about every two
years.
• Power cord
• Rack-mount kit
• Warranty card
