1. OUTLINE
The CD Encoder DA-7000Ais designed for converting CD-ROM data or musicrecorded
on DIGITAL AUDIO Tapes (DAT)for professional use or U-matic VCR into EFM
signals based on the COMPACT DISC (CD) standards.
Bycombining with the CD-WO Writer DD-7200A a CD-WO system can be constructed.
2. FEATURES
(1) The unit conforms to the RED BOOK, YELLOW BOOKandORANGEBOOK PARTII
(November 1990), and allowsconstruct ion ofa CD-WO systemthrough
combination with a CD-WO Writer DD-7200A.
(2) The controlfunctionsnecessary forthe encoder, includinggeneration ofthe
subcode, are all controlled through the GP-IB. System-incorporation is
facilitated by possiblecontrol of the VCR and DAT through the GP-IB.
(3) Through applicat ion of LSI in the CD Encoder, circuitry has been
simplified and reliability increased.
(4) ConnectingU-matic VCR, professional DAT equipment,etc., is easyowing
to the 3 datainput interface systems: SDIF, AES/EBU Digital Audio Interface
and parallei input.

Mi0~F i signify minutes / seconds / frame number intens and
single digits.
1)P.START(S#MioMiSioSiFi0Fi$/)
In thecaseof normal cutting and CD-WO uninterrupted writing,
this command is used to specify the program area s starting time
(00M00S00F)
In thecaseof CD-WO incremental writing, the command is used to
specify the starting timeforthe additional writing.
2)M. START (S7MioMiSioSiF10Fi$/)

data (inthecase of CD-ROM, etc. ) should actual ly start
inside the track. Inthecase of the disc' s first traci - if
this is amelody - the specified timeshould be within the
range of00M02s00F -00M 03s00F. Ifthe first track is
to containdata,the setting should be 00M02S00F.

setting deviates fromtheM. START, this command is used when
no interval should be left between melodies,or - inthecase of
data - no pregap.
1 4

5)M.STOP(S4MioM1Si0S1F10F1$/)
Indicates the ending ofthe melody or data. This also becomes
the start time ofthe next track. Inthe case of normal cutting
and CD-WO uninterrupted wr i t ing, usethe P. STOPforthe
program area's last melody or datastop. In the case of
incremental writ ing, also usethe P. STOPforthe last melody
ordatastop.
6) P.STOP (S%MIOMISIOSIFIOFI$/)
In the case of normal cutting and CD-WO uninterrupted writing,
this indicates the program area' s last melody or datastop and
becomes the start time of theLEAD-OUT area. Inthe case of
incremental writing, it indicates the ending time of the last
melody or data to be added.
When receiving this command,the encoder terminatesinput.
[E 6S 0 5] ControlBit Setting
(Function) Used tosetthe controlbit for each track.
(Command format) B3~ B0 signifies the value 0 or1; B3=4/2 CHANNEL; B2=

(Function) Command forthe ORANGEBOOK PART II
When writing to PCA, this command isused to setthePARTITION
number. After comp1e t i ng the setting, the encoder
calculates the ATIME value ofthe first subcodefor PCA
writing start based onthe previously set STARTTIME OF
LEAD-IN and the part it ion number sett ing.
(Command format) E6S11 !NiN2$/
00 < NiN2 ^ 99 (NiN2 are numeric values between 0 ~ 9)
