Abstract
Systems and methods are provided for reading data encoded on an optical card as a series of binary pits formed within optical-card tracks separated by an average optical-card track pitch. A translator and a compact-disc laser head are provided. The compact-disc laser head reads data from a compact disc having data encoded as a series of binary pits formed within compact-disc tracks separated by an average compact-disc track pitch. The translator moves the optical card linearly relative to the compact-disc laser head in a direction of motion. The compact-disc laser head is oriented relative to the direction of motion to accommodate a difference between the average optical-card track pitch and the average compact-disc track pitch.
Claims19
A system for reading data encoded on an optical card as a series of binary pits formed within a plurality of optical-card tracks separated by an average optical-card track pitch, the system comprising:
- a translator;
- and
- a compact-disc laser head adapted to read data from a compact disc having data encoded as a series of binary pits formed within a plurality of compact-disc tracks separated by an average compact-disc track pitch,
- wherein:
- the translator is adapted to move the optical card substantially linearly relative to the compact-disc laser head in a direction of motion;
- and
- the compact-disc laser head is oriented relative to the direction of motion to accommodate a difference between the average optical-card track pitch and the average compact-disc track pitch.
A method for reading data encoded on an optical card as a series of binary pits formed within a plurality of optical-card tracks separated by an average optical-card track pitch, the method comprising:
- translating the optical card substantially linearly relative to a compact-disc laser head in a direction of motion, the compact-disc laser head being adapted to read data from a compact disc having data encoded as a series of binary pits formed within a plurality of compact-disc tracks separated by an average compact-disc track pitch and oriented relative to the direction of motion to accommodate a difference between the average optical-card track pitch and the average compact-disc track pitch;
- and
- reading the data from the translating optical card with the compact-disc laser head.
A system for reading data encoded on an optical card as a series of binary pits formed within a plurality of optical-card tracks separated by an average optical-card track pitch, the system comprising:
- means for reading data from a compact disc having data encoded as a series of binary pits formed within a plurality of compact-disc tracks separated by an average compact-disc track pitch;
- and
- means for translating the optical card along a direction of motion oriented relative to the means for reading to accommodate a difference between the average optical-card track pitch and the average compact-disc track pitch.
