- Model 1 (tray loading)
The model 1 Sega CD uses a KSS240A laser.
- Model 2 (clamshell)
There are two variations of the model 2 sega cd. The one with a silver ring spindle uses a Samsung SOH-0T4. The all black spindle variation uses a Sony KSS210A lens or Sony KSS210B lens. A KSS210B can replace a KSS210A on a sega cd using the KSS210A, but a KSS210A can't replace a KSS210B.
A Sanyo CF-C93 laser was used in the CDX as well as the Goldstar 3DO.
The X'eye uses the same pickup as the Model 2 Saturn. Therefore a JVC OPTIMA6, JVC OPTIMA6S or JVC OPTIMA150S will work.
- Model 1 (oval buttons)
Model 1 systems use the JVC EMW10447. The JVC OPTIMA6 or JVC OPTIMA150S can be used as replacements.
- Model 2 (round buttons)
Similar to the Model 1, a JVC OPTIMA6, JVC OPTIMA6S or JVC OPTIMA150S can be used as replacements.
