Summary
High-speed laser recording was demonstrated on metallic and organic thin films. This method achieved one million spots per second with a 38 milliwatt laser, enabling fine 2-micron line widths.
Area of Science:
- Materials Science
- Optical Engineering
- Data Storage
Background:
- Advancements in data storage necessitate high-density recording media.
- Thin film materials offer potential for novel recording applications.
Purpose of the Study:
- To demonstrate scan-line recording on metallic and organic thin films using a moving laser spot.
- To evaluate the recording rates and resolution achievable with this technique.
Main Methods:
- Utilized a focused laser beam to perform scan-line recording.
- Employed metallic and organic thin films as recording media.
- Measured recording rates and resulting line widths.
Main Results:
- Achieved scan-line recording on both metallic and organic thin films.
- Obtained recording rates of approximately one million spots per second.
- Produced recorded line widths of approximately 2 microns with 38 milliwatt laser power.
Conclusions:
- Scan-line laser recording is feasible on metallic and organic thin films.
- The method supports high recording rates and fine resolution, suitable for data storage applications.
