Abstract: A magnetic recording method using a magnetic head to record information in an information recording medium and read the information recorded on the information recording medium is such that the temperature of a portion of the information recording medium on or from which information is recorded or read is changed in order to record or read information. A disk device having the ability to record and read information comprises a magnetic head for recording information by applying a given magnetic field to an information recording medium and reading the information from the information recording medium; and a temperature changing mechanism for changing the temperature of a portion of the information recording medium on or from which information is recorded or read. The magnetic head is moved to the portion of the medium in which a temperature change is produced by the temperature changing mechanism, whereby information is recorded or read.

Abstract: A method for overwriting information in a magneto-optical memory medium which includes a simultaneous writing and erasing step of continuously irradiating a written information-carrying area of the recording layer of the memory medium with two different pulses from a single laser beam head in accordance with information to be written, regardless of the presence or absence of written information. A variation includes irradiating the written information-carrying area with an erasing pulse from a laser beam head, regardless of the presence or absence of written information, and then selectively irradiating the information-erased area with a writing pulse from another laser beam head in accordance with information to be written. According to these methods, it becomes possible to carry out a simple and high-speed overwriting with an increased and stabilized bit positioning accuracy.

Abstract: An optical disk provided with read-exclusive regions where previously recorded information can be read, and with write-enable regions where information can be written. Information not desired to be rewritten can be recorded on the read-exclusive regions. The write-enable regions are open to users to freely add information thereto and to re-write information recorded. This optical disk can thus be used in various fields.
