    • The present invention relates to a hard disk drive performing a seek control method using a multi-sinusoidal wave acceleration profile, where the seek control method is capable of coping with a variation in a voice coil motor driving current due to variances in a peripheral environment. The seek control method of the present invention includes: calculating a seek time scaling (STC) related to variations in a voice coil motor (VCM) driving current due to variation in a peripheral environment; calculating an acceleration distance ratio (ALR) of an acceleration distance to a maximum seek distance without a coast mode according to the STC; calculating position profiles in an acceleration mode, the coast mode and a deceleration mode, respectively, using both the STC and the ALR; and performing a seek operation by generating the VCM driving current according to the position profiles and applying the VCM driving current to a VCM.

    • The present invention relates to a lazy bulk insertion method for moving object indexing, which utilizes a hash-based data structure to overcome the disadvantages of an R-tree, and uses two buffers to simultaneously store operations in the buffers and process queries stored in the buffers, so that the overall update cost can be reduced. In the lazy bulk insertion method, a buffer is substituted and a state of the buffer is changed to a deactivated state if an input query cannot be stored in the buffer. Operations stored in the deactivated buffer are sequentially analyzed, information about objects corresponding to respective operations is obtained from a direct link to analyze the operations, and thus the operations are aligned on the basis of object IDs. Operations, aligned in ascending order of spatial objects, are identified depending on respective objects, effectiveness of the operations is determined, and thus the operations are realigned on the basis of terminal node IDs. The number of insert operations and the number of delete operations are counted for each terminal node, and variation in the number of empty spaces in the terminal node is obtained, thus splitting and merging of the terminal nodes is predicted. A processing sequence of queries is reorganized so as to reduce variation in the node on the basis of the predicted information.
    • 本发明涉及一种用于移动对象索引的延迟批量插入方法,其利用基于散列的数据结构来克服R树的缺点,并且使用两个缓冲器来同时存储缓冲器中的操作和存储在 缓冲区,从而可以降低总体更新成本。 在惰性批量插入方法中,如果输入查询不能存储在缓冲区中,则替换缓冲区,并将缓冲区的状态更改为禁用状态。 顺序地分析存储在去激活缓冲器中的操作,从直接链接获得关于对应于各个操作的对象的信息,以分析操作,因此基于对象ID来对齐操作。 根据各个对象来识别按空间对象的升序排列的操作,确定操作的有效性,并且因此基于终端节点ID对操作进行重新排列。 对每个终端节点计数插入操作次数和删除次数,得到终端节点空闲空间数量的变化,从而预测终端节点的分裂和合并。 重新组织查询的处理顺序,以便基于预测信息来减少节点的变化。
