Research output: Contribution to journalConference articlepeer-review


Two media configurations are identified as suitable for direct overwrite, by light intensity modulation, within a fixed bit-cell encoding scheme. Unlike previously proposed media of comparable complexity, these materials do not require a second (intialization) magnet within the drive. Key to successfull operation is the use of small marks and precise synchronization of old and new marks inherent within fixed bit-cell encoding. Latitudes in alignment and power for direct overwrite are assessed.
