Re - - harvey concerns
First an example - - Place a music CD into the CD-DVD player . . . . Open Windows Explorer and navigate to that CD, and open it (not play it) . . . That is, right-click the CD-DVD-drive and choose "Explorer" in the drop-down menu. . . . You should now see Track 01, Track 02, Track 03, and so on. . . . Copy all those Tracks and place them in a folder on the Desktop. . . . Now try to play those tracks that you placed in that Desktop folder. . . . They won't play, as all you really copied were the Track names (Track01, Track02. etc.).
In this case, the music CD, one must use a CD-music-ripping software to get that music off the CD. . . . Say, the free CDex software, which I prefer. . . . The music on the CD is stored using (say) cylindrical coordinates (data block at so-&-so radius and angle theta). . . To copy that music off the CD, one essentially must copy the data plus its cylindrical coordinates used by the CD and then convert all that to the coordinate system used in Windows.
The Windows 32-bit coordinate system is really a mess, as there are not enough digits in a 32-bit system to uniquely identify all the miniscule magnetic rods on the hard-drive. . . To get around this 32-bit limitation, Windows works with Sectors and Clusters, each sub-division with its own numbering system. . . . Then there is the problem that a hard-drive can contain five internal-storage-disks, ten magnetic heads, so that the Windows's numbering system must be able to distinguish between what disk is the data on, and the disk's top-side-or bottom-side
Summarizing, to copy a music CD to a hard-drive, one must use some ripping software that will do all the mathematics of taking the data off the CD and converting to that which Windows can use
The same goes with Karaoke CD+G disks. . . . There is Music therein that must be properly ripped off the CD. . . . Plus, there is Graphics, most likely elsewhere on the CD, that also must be properly ripped off the CD. . . . And, there is some type of correlation of the Music with the Graphics that also must be captured and preserved
This means that, to copy a Karaoke CD+G disk to the hard-drive, one must use a "Karaoke CD+G ripping" software or use a CD-cloning software. . . .(CD-cloning software - - Alcohol 120%, CloneCD, CDRWin, Blind Read-Write, etc). . . .
The "Karaoke CD+G ripping" software will allow you to play the Karaoke from your hard-drive and watch the bouncing ball on the lyrics on your monitor. . . . Most likely the "Karaoke CD+G ripping" software will give different placement on the hard-drive depending on what specific software you use. . . . Most likely that generated on the hard-drive by one "Karaoke CD+G ripping" software will not be playable by another "Karaoke CD+G ripping" software
The CD-cloning software will make an exact-image of that Karaoke CD+G disk from which you cam make duplicate CD+G disks. . . . Believe that the CD-Cloning softwares must be properly set in the Prefernces to handle a CD+G disk. . . (Seems, I recall that CDRWin did this). . . . Also, most CD-cloning softwares will also allow you to create a section on the hard-drive that simulates a CD, and if the image is placed therein, will allow you to play the Karaoke CD+G from your hard-drive
I have been out-of-touch with Karaoke CD+G disks for some time now, so do not know what is currently available. . . . But try searching around for a CD+G ripping software. . . . . When I last did this CD+G several years ago, I had problems in that I would get the synchronization perfect, then store the end-product on my hard-drive, only to find that next day the synchronization went astray when recalled
