Abstract
The authors demonstrate that the bits of a Compact Disc – Read Only Memory (CD-ROM) can be read without a
photodiode (PD). A commercial CD-ROM drive was used and left unmodified except a beam splitter was removed which would
route the light to a PD. This allowed for the reflected light to be incident on the laser within the laser package itself. By
monitoring fluctuations in the voltage across the laser diode under constant-current injection, it was possible to read and
interpret the bits from a spinning CD-ROM.
