Method and apparatus to encode information in, and dispose a human-readable pattern on, a rotatable data storage medium

摘要

A method to store first information in a rotatable data storage medium and to dispose second information on a rotatable data storage medium. An apparatus comprising a constant linear velocity drive servo, a laser device, and a computer useable medium having computer readable program code disposed therein for sequencing laser irradiations to encode first information in a rotatable data storage medium and to dispose second information on a rotatable data storage medium. A rotatable disk storage medium having first information encoded in the information area and at least one human-readable pattern disposed on the clamp area and/or the information area.
