BACKGROUND OF THE INVENTION
1. Description of the Related Art
It is known in the art to use an optical disk for the storage of software, music and film. However, the conventional optical disk has a relatively large size, and is thus inconvenient to handle.
2. Field of the Invention
The invention relates to a data storage medium and to an apparatus for reading the data storage medium, more particularly to a portable data storage medium that has a relatively large memory capacity, and to an apparatus for reading the data storage medium.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a portable data storage medium having a relatively large storage capacity.
Another object of the present invention is to provide an apparatus for reading the data storage medium of this invention.
According to one aspect of the present invention, a data storage medium is adapted for storing optically detected information. The data storage medium includes a rectangular card body having first and second surfaces, at least one of which is formed with a data storage track having a plurality of parallel and equally spaced apart track sections that are adapted to be stored with the optically detected information.
According to another aspect of the present invention, an apparatus is adapted for reading optically detected information stored in a data storage medium. The data storage medium includes a rectangular card body having first and second surfaces, at least one of which is formed with a data storage track having a plurality of parallel and equally spaced apart track sections stored with the optically detected information. The apparatus includes a carrier unit, first moving means, optical detector means, second moving means and controller means.
The carrier unit is adapted to be loaded with the data storage medium thereon.
The first moving means, which is associated operably with the carrier unit, moves the carrier unit back and forth between first and second limit positions along a first axis parallel to the track sections.
The optical detector means is adapted for reading the optically detected information stored in one of the track sections when the carrier unit is moved by the first moving means along the first axis.
The second moving means, which is associated operably with the optical detector means, moves the optical detector means along a second axis transverse to the first axis.
The controller means is coupled electrically to the first and second moving means and the optical detector means. The controller means receives the optically detected information read by the optical detector means, and activates the second moving means to move the optical detector means by a predetermined distance along the second axis upon detection that the first moving means has moved the carrier unit from one of the first and second limit positions to the other one of the first and second limit positions.
