Olha.. Existe outra forma.. Tenta esta..
Para Abrir:

function OpenCD(Drive : Char) : Boolean;
Var
Res : MciError;
OpenParm: TMCI_Open_Parms;
Flags : DWord;
S : String;
DeviceID : Word;
begin
Result:=false;
S:=Drive+�:�;
Flags:=mci_Open_Type or mci_Open_Element;
With OpenParm do
begin
dwCallback := 0;
lpstrDeviceType := �CDAudio�;
lpstrElementName := PChar(S);
end;
Res := mciSendCommand(0, mci_Open, Flags, Longint(@OpenParm));
IF Res<>0 Then exit;
DeviceID:=OpenParm.wDeviceID;
try
Res:=mciSendCommand(DeviceID, MCI_SET, MCI_SET_DOOR_OPEN, 0);
IF Res=0 Then exit;
Result:=True;
finally
mciSendCommand(DeviceID, mci_Close, Flags, Longint(@OpenParm));
end;
end;

Para Fechar:

function CloseCD(Drive : Char) : Boolean;
Var
Res : MciError;
OpenParm: TMCI_Open_Parms;
Flags : DWord;
S : String;
DeviceID : Word;
begin
Result:=false;
S:=Drive+�:�;
Flags:=mci_Open_Type or mci_Open_Element;
With OpenParm do
begin
dwCallback := 0;
lpstrDeviceType := �CDAudio�;
lpstrElementName := PChar(S);
end;
Res := mciSendCommand(0, mci_Open, Flags, Longint(@OpenParm));
IF Res<>0 Then exit;
DeviceID:=OpenParm.wDeviceID;
try
Res:=mciSendCommand(DeviceID, MCI_SET, MCI_SET_DOOR_CLOSED, 0);
IF Res=0 Then exit;
Result:=True;
finally
mciSendCommand(DeviceID, mci_Close, Flags, Longint(@OpenParm));
end;
end;
