摘要： With this invention, the reference velocity data corresponding to the number of the remaining tracks to the destination target position of the optical head is stored, and on the basis of the reference velocity data, the velocity of the optical head is controlled. The reference velocity data contains the maximum velocity region data and deceleration data for the optical head. The deceleration data is obtained by subtracting the steady-state deviation from the velocity trajectory. The steady-state velocity deviation is obtained from the response characteristic of the optical-head velocity control system. When the optical head is moved, the reference velocity data corresponding to the number of the remaining tracks between the current position of the optical head and the destination target position is read. On the basis of this read-out reference velocity data, a linear motor for driving the optical head is controlled.
摘要翻译：利用本发明，存储对应于光头的目的地目标位置的剩余轨道的数量的参考速度数据，并且基于参考速度数据，控制光学头的速度。参考速度数据包含光头的最大速度区域数据和减速数据。通过从速度轨迹中减去稳态偏差来获得减速数据。稳态速度偏差由光头速度控制系统的响应特性得到。当光头移动时，读取与光头的当前位置和目的地目标位置之间的剩余轨道数量相对应的基准速度数据。基于该读出的基准速度数据，控制用于驱动光学头的直线电动机。

摘要： To exclude any unauthorized device from a system and thereby prevent illegal use of content data, a memory card 10 stores a service key Ksrv for encrypting content key data Kc in a hidden area 14. The memory card 10 stores answer data AC to be obtained when question data Q is fed to a host function F possessed by an authorized host device 20, with encryption applied to the answer data AC by the service key Ksrv. When the question data Q is provided to the host device 20, answer data AH is obtained based on the question data Q and the host function F. A comparison unit 122 judges match or mismatch of the answer data AH and the answer data AC. When they match, the memory card 10 decrypts the content key data Kc encrypted by the service key Ksrv and sends it to the host device 20.

摘要： A method is provided for generating a color chart for a printer, which color chart comprises a plurality of elements. The method comprises obtaining reference color data representing colors output by the printer, when the printer is in a reference state. Further, comparison color data representing colors output by the printer, when the printer is in another state is obtained. Differences in color between corresponding elements of the reference color data and the comparison color data are determined and at least one region of the output color space of the printer is classified as a linear region in which the differences vary substantially linearly. The method includes selecting colors of the elements of the color chart on the basis of the linear region.
