Information memory medium and information recording/holding process making use of the medium |
摘要 |
Provided is an information memory medium comprising a recording layer containing a polymeric liquid crystal having a ferroelectric chiral smectic phase, wherein said polymeric liquid crystal comprises a polymeric liquid crystal having a temperature region, in which its electric-field response time changes by the factor of not less than 200 times, within a temperature range of the ferroelectric chiral smectic phase on the side of higher temperatures than its glass transition temperature.
