光记忆存储的主要优点是能够同时检索整页的信息,而其它存储技术只能逐个比特地检索。光记录技术的比特并行存储格式不仅能使数据转换速率超过每秒10~9比特,而且能缩短存取时间。但是,目前采用光折射材料和连续光谱烧孔材料的并行光记录技术如没有新的突破,其存取速率仍比现有的半导 The main advantage of optical memory storage is the ability to retrieve full page information simultaneously, whereas other storage technologies can only retrieve on a bit-by-bit basis. The bit-parallel storage format of optical recording technology not only enables data conversion rates of more than 10 to 9 bits per second, but also reduces access time. However, the current parallel optical recording technology using photorefractive materials and continuous spectrum hole burning materials, if no new breakthrough, the access rate than the existing semiconductors
