you can try the following function:

function IsSrcDirCDROM()
    NUMBER nvResult;
    STRING svResult;
begin
    ParsePath(svResult, SRCDIR, DISK);
    GetSystemInfo ( DRIVE, nvResult, svResult );
    if (nvResult = IS_CDROM) then
        return TRUE;
    else
        return FALSE;
    endif;
end;
