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： 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： 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 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.
