Abstract

The implementation and testing of a 3Φ (1,7) code on optical disk recorders for improved packing density is described with details concerning data formatting and CODEC electronics. Comparative test results presented relate off-disk bit-error-rate (BER) to linear packing density (LPD) for 3Φ (1,7), delay modulation (DM), and straight NRZ-L codes. 3Φ (1,7) improves LPD by more than 25% over the previously used DM code.
