Abstract
A storage medium with electronic paper is provided with a disk drive that can refresh the display on the electronic paper using a simple arrangement. A disk drive includes a motor that generates rotational force and a drive shaft support for clamping a disk thereon by contacting with the disk and for turning the disk thereon by the rotational force. The drive shaft support includes at least one output terminal for outputting an electrical signal. If the disk includes electronic paper on which the display is refreshable in response to the electrical signal, the at least one output terminal of the disk drive is arranged so as to contact with at least one input terminal that is arranged on the disk to supply the electrical signal to the electronic paper.
Claims14
A data processor for writing data on a data area of a storage medium having content data representing a content, the processor comprising:
- a drive to be loaded with the storage medium in a removable position;
- a control section, which is provided for one of the storage medium, the data processor itself, and a display device connected to the data processor and which is electrically connected to electronic paper, on which information displayed is updatable, and controls update of information displayed on the electronic paper;
- and
- a processing section, which reproduces the content data written on the storage medium and which generates information representing a title of the content, which is the content's own identification information based on the content data,
- wherein, when reproduction of the content is finished, the control section writes the title of the content and a description indicating that the content has been viewed on the electronic paper.
A data processor for reading and/or writing content data from/on a data area of an optical disk,
- wherein electronic paper, which turns with the optical disk and on which information displayed is updatable, is provided for the optical disk, and
- wherein the information displayed on the electronic paper is updated when a voltage is applied to the paper but is unchanged when no voltage is applied to the paper, and
- wherein the data processor comprises:
- a drive to be loaded with the optical disk in a removable position;
- and
- a control section, which is electrically connected to the electronic paper provided for the optical disk, and controls update of information displayed on the electronic paper by regulating the voltage applied,
- wherein the electronic paper stores information about the specific gravity of particles in the electronic paper, and
- wherein when the number of revolutions of the optical disk decreases to a predetermined value or less, the control section updates the information displayed on the electronic paper by reference to the number of revolutions of the optical disk and the information about the specific gravity of the particles in the electronic paper.
