Example embodiments relate to a green-light emitting device including a quaternary quantum well on a vicinal c-plane. The light-emitting device includes a substrate having a vicinal c-plane surface and a light-emitting layer on the vicinal c-plane surface of the substrate. The light-emitting layer includes a quantum well layer of AlInGaN and quantum barrier layers of InGaN disposed on and under the quantum well layer respectively, and 0&#x3c;x&#x3c;1, 0&#x3c;y&#x3c;1, and 0&#x3c;z&#x3c;1.

An address generator in the demodulator for an optical disk system generates addresses necessary for recording demodulated EFM in a predetermined area of a memory in the demodulator of an optical disk system, reading and recording the data for an error detection and correction of an EFM demodulation signal, and reading the data for converting digital signals for performing error correction into analog signals by using a scrambling counter and a decoder, thereby enabling quick generation of addresses while reducing chip space.
