Along with dedicated karaoke machines, other consumer devices that play CD+G format CDs include the NEC TurboGrafx-CD (a CD-ROM peripheral for the TurboGrafx-16) and Turbo Duo, as well as the Japan-only successor the PC-FX, the Philips CD-i, the Sega CD, Sega Saturn, [5] the JVC X'Eye, the 3DO Interactive Multiplayer, the Amiga CD32 and ...
In the event the movie was longer than what could be stored on two sides of a single disc, manually swapping to a second disc was required at some point during the film (one exception to this rule was the Pioneer LD-W1, which featured the ability to load two discs and to play each side of one disc and then to switch to playing each side of the ...
The CD-i Bridge format, defined in Philips' White Book, is a transitional format allowing bridge discs to be played both on CD-ROM drives and on CD-i players. The CD-i Digital Video format was launched in 1993 containing movies that could be played on CD-i players with a Digital Video Cartridge add-on.
The CD-ROM itself may contain "weak" sectors to make copying the disc more difficult, and additional data that may be difficult or impossible to copy to a CD-R or disc image, but which the software checks for each time it is run to ensure an original disc and not an unauthorized copy is present in the computer's CD-ROM drive.

One major drawback to these copy-protected discs is that most will not play on either computer CD-ROM drives or some standalone CD players that use CD-ROM mechanisms. Philips has stated that such discs are not permitted to bear the trademarked Compact Disc Digital Audio logo because they violate the Red Book specifications.
This allows a DVD drive to focus the beam on a smaller spot size and to read smaller pits. DVD lens supports a different focus for CD or DVD media with same laser. With the newer Blu-ray Disc drives, the laser only has to penetrate 0.1 mm of material. Thus the optical assembly would normally have to have an even greater focus range.
The 1541 was the standard floppy disk drive for the Commodore 64, with nearly all disk-based software programs released for the computer being distributed in the 1541 compatible floppy disk format. The 1541 was very slow in loading programs because of a poorly implemented serial bus , a legacy of the VIC-20 .
The SMD interface is based upon a definition of two flat interface cables ("A" control and "B" data) which run from the disk drive to a hard disk drive interface and then to a computer. This interface allows data to be transferred at 9.6 Mbit/s. The SMD interface was supported by many 8 inch and 14 inch removable and non-removable disk drives.
