摘要： By adjusting the advancement rate of an optical data storage medium in response to the amount of data to be written, and operating a laser with a minimum amount of write laser power level for the particular advancement rate to achieve a desired level of write effectiveness, data signals are written to the optical medium with a minimum amount of power. Where the optical medium comprises an optical disk, choosing the rate of disk rotation selectively establishes the advancement rate. Similarly, where the optical medium comprises an optical tape, choosing the rate of tape advancement from source reel to take-up reel selectively establishes the advancement rate. Preferably, the advancement rate is increased or decreased depending upon whether a greater or lesser quantity or write length of data resides in a write queue. The invention may be implemented, for example, to provide a process, apparatus or program storage medium useful for laser storage of digital data signals to an optical data storage medium with minimal power consumption.

摘要： The utilization of a level of a data storage hierarchy is monitored and the data in such level is manipulated in response thereto. In a data storage hierarchy including an automated storage library, the utilization is a mount rate relative to the maximum possible mount rate. When the combined utilization of all of the libraries exceeds a predetermined value, data is promoted from the most utilized library (or libraries) to a higher level in the data storage hierarchy until the combined utilization of all of the libraries is sufficiently reduced. By reducing the combined utilization of all of the libraries, the average queue time for library mount requests is prevented from becoming excessively long relative to the average library mount cycle time. When the difference between the utilization of the most utilized library and the least utilized library exceeds a predetermined value, data is passed from the most utilized library (or libraries) to the least utilized library (or libraries) until the difference is sufficiently reduced. By reducing the difference in utilization between the most and least utilized libraries, mount activity is evenly distributed among the libraries.
摘要翻译：监视数据存储分层级的使用，并响应于此处理这种级别的数据。在包括自动存储库的数据存储层次结构中，利用率是相对于最大可能安装速率的安装速率。当所有库的组合利用超过预定值时，将数据从最常用的库（或库）升级到数据存储层级中的较高级别，直到充分减少所有库的组合利用。通过减少所有库的组合利用率，库安装请求的平均队列时间相对于平均库安装周期时间将不会变得过长。当使用最多的库和最少使用的库之间的差异超过预定值时，数据从最常用的库（或库）传递到最不利用的库（或库），直到差异被充分地减少。通过减少最少和最少使用的库之间的利用差异，挂载活动在库之间均匀分布。
