Abstract

Today, although Blu-ray, DVD, CD, hard disk drive, solid state drive, electrically erasable programmable read-only memory (EEPROM) are available, the lifetime of stored data is short. To store large amounts of data longer than 100 years, long-term data storage media are necessary. Moreover, systems designed for use in space require highly radiation-tolerant memory. As long-term data storage media this study demonstrates that a polymer-dispersed liquid crystal holographic memory has a high radiation tolerance by using a cobalt 60 gamma radiation source. Results show that the holographic memory radiation tolerance is more than 667 times higher than EEPROM radiation tolerance.
