摘要： According to one embodiment, a storage device includes, when power is supplied to a storage unit, counting of an elapsed time is started. If a command is input from a host device, and the elapsed time from input of a previous command to input of a current command is calculated based on time information clocked by the host device and on a counter value counted until the corresponding command is input. Matching of the time information is determined based on a temporal relation between the adding result of adding the calculated elapsed time to the time information included in the previous command and the time information included in the current command. When the mismatching is determined, data in the storage unit is invalidated.

摘要： According to one embodiment, a memory device includes a third partial key write module, an encryption key write module, and a decryption module. The third partial key write module is configured to combine a second partial key received from the current host device with the first partial key in the partial key memory device and to write a generated third partial key into the volatile memory after the device authentication. The encryption key write module is configured to combine the third partial key with the second user authentication information and to write a generated encryption key into the volatile memory after the user authentication. The decryption module is configured to decrypt the encrypted data based on the encryption key in the volatile memory based on a read request received from the current host device and to output obtained data to the current host device when the user authentication has succeeded.

摘要： A read retry of an MSR medium is executed while changing a setting of a reproducing magnetic field. Parameter set values of a successful read retry are stored as statistic information. When changes of the set values for defaults increase, the defaults are updated. The parameter set information of a retry success is stored as statistic information. In a new read retry, the parameter set information of a high success ratio is selected from the statistic information and the retry is executed.

摘要： There is provided a data storage device which reads data from and/or writes data to a memory medium, comprising: an acquisition unit for acquiring management information which is recorded by a predetermined form in said memory; and a controller for converting the management information into another form. The controller rearranges the management information to convert the management information into another form, and also the controller restores the converted management information to the predetermined form according to a relationship between a first identifier recorded on the memory medium and a second identifier recorded in the data storage device. When, for example, the two identifiers match, the acquisition unit can acquire the management information, and the reading and writing of data is enabled. When the two identifiers do not match, restoration of the management information to a predetermined form is not effected, so that the acquisition unit can not acquire the management information and the reading and writing of data is disabled.
摘要翻译：提供了一种从存储介质读取数据和/或将数据写入存储介质的数据存储装置，包括：获取单元，用于获取以预定形式记录在所述存储器中的管理信息; 以及用于将管理信息转换成另一形式的控制器。控制器重新排列管理信息以将管理信息转换为另一种形式，并且控制器还根据记录在存储介质上的第一标识符与记录在数据存储器中的第二标识符之间的关系将所转换的管理信息恢复为预定格式设备。当例如两个标识符匹配时，获取单元可以获取管理信息，并且能够读取和写入数据。当两个标识符不匹配时，管理信息恢复到预定的形式不被实现，使得获取单元不能获得管理信息，并且数据的读取和写入被禁止。

摘要： It is provided a data storage device which reads data from and/or writes data to a memory medium, comprising: a storage unit for storing a first identifier; an identifier acquisition unit for acquiring a second identifier recorded on a memory medium which is set to said data storage device; and a controller for comparing said first identifier with said second identifier, and controlling to access to said memory medium for data reading and/or writing according to a relationship between said first identifier and said second identifier. For example, when the first identifier does not match the second identifier, the controller inhibits access to the memory medium for the reading and writing of data. But when the first and the second identifiers match, the controller permits access to the memory medium for the reading and writing of data. Since the storage device having an identifier which differs from the identifier recorded on the memory medium inhibits access to the memory medium for the reading and writing of data, the secrecy of data recorded on the memory medium is ensured.
摘要翻译：提供了一种从存储介质读取数据和/或将数据写入存储介质的数据存储装置，包括：存储单元，用于存储第一标识符; 标识符获取单元，用于获取记录在设置于所述数据存储装置的存储介质上的第二标识符; 以及控制器，用于将所述第一标识符与所述第二标识符进行比较，并且根据所述第一标识符和所述第二标识符之间的关系控制对所述存储介质的访问以进行数据读取和/或写入。例如，当第一标识符与第二标识符不匹配时，控制器禁止对存储介质的访问以读取和写入数据。但是当第一和第二标识符匹配时，控制器允许访问存储介质以读取和写入数据。由于具有与记录在存储介质上的标识符不同的标识符的存储装置禁止访问用于数据的读取和写入的存储介质，因此确保了记录在存储介质上的数据的保密性。

摘要： A rotation control method controls rotation of a CAV system recording medium which has a plurality of zones divided in a radial direction thereof. The rotation control method detects a state within a memory which temporarily stores write data to be written on the recording medium and/or read data read from the recording medium, and switches and controls a rotational speed of the recording medium based on the detected state of the memory, depending on an area which is accessed of a plurality of areas of the recording medium dividing the recording medium in the radial direction thereof.
