An optical card has many advantages such as portability, large storage capacity, and low cost. We have developed an optical card reader/writer using two optical sources: a laser diode (LD) for writing and an LED for reading. We have demonstrated that this method is effective for stable and high speed reading/writing because of (1) wide tracking dynamic range, (2) stable data reading signal vs. tracking error, (3) no card damage by reading light, (4) two track reading, and (5) direct read during write.
