Electronic device and data transfer method

According to one embodiment, an electronic apparatus includes a first module and a second module. The first module receives a remote command from another electronic apparatus and transmits a response to the remote command to the other electronic apparatus. The remote command includes command type information indicating a type of the local command. The second module issues one or more local commands including the local command to the storage device and transmits a first response from the storage device to the other electronic apparatus by storing the first response into a second response to the remote command, in accordance with a process specified by the command type information in the remote command.

Remote access system, electronic apparatus and method of processing remote access

According to one embodiment, an access control apparatus includes a medium communication module configured to perform communication with a removable medium, a access module configured to perform access to the removable medium using the communication module, a wireless communication module configured to perform wireless communication with a external device, and to receive access request to the removable medium, and a controller configured to assign an access right to access the removable medium to one of the access module and the external device, the control module assigning the access right in response to a request of assignment of the access right, the request being transmitted from the external device or the access module.

Controlling access to a removable medium from a module and an external device

An example hard disk drive (HDD) comprising a magnetic disk and a ramp within the HDD is disclosed. A slit is disposed between a ramp body and a flange.

Flexible ramp in a hard disk drive

A magnetic disk device including a disk, a spindle motor, a base for supporting the spindle motor and the disk, a slider includes a head element. The device also includes an actuator including arms for supporting the slider and a coil of a voice coil motor for rotating the arms, wherein a first natural bending frequency of the coil is less than a first natural bending frequency of the arms.

Magnetic disk device

Embodiments of the present invention relate disk drives, and in particular to realizing a positioning accuracy equal to that of an actuator having the mountable maximum number of suspensions, in an actuator having the smaller number of suspensions than the mountable maximum number. An embodiment of a magnetic disk device includes an actuator having an arm to which a suspension for applying a predetermined load onto a slider with a magnetic head is attached, and an arm to which a plate is attached instead of having the suspension. The plate attached to the arm in place of the suspension has a partially small section with respect to a section perpendicular to an arm longitudinal direction (constricted part), and the constricted part is located between a plate leading end and an arm attachment part.

When content owned by a source device are played back in a rendering device, a content key is transferred from the source device to the rendering device via a secure session every time playback is carried out. Then, encoded content are decoded and played back to be outputted by using the transferred content key so as to discard the content key after the end of playback.

Information terminal

Embodiments of the present invention help to reduce out-of-plane excitation force exerted on a coil in a voice coil motor of a magnetic disk drive, so that vibration of a magnetic head is suppressed. According to one embodiment, a voice coil motor has a flat magnet that faces a coil, and generates a magnetic field, and yokes that apply the magnetic field generated by the magnet to the coil. The magnet is provided with a magnetic flux guiding section, absorbing leakage flux from the magnet, on a most distal end of the magnet as viewed from a pivot axis. A most distal part of the coil as viewed from the pivot axis, may be situated in an outer side with respect to the most distal end of the magnet, and the magnetic flux guiding section is provided between the most distal end of the magnet and the most distal part of the coil.

Magnetic disk drive and voice coil motor

According to one embodiment, a content protection device includes a writing module configured to write protection information into file management information item in order to protect a content which is specified to be protected, wherein the writing module is configured to write the protection information corresponding to sectors which stores content key management information file includes content key link information item includes content key position information item of encrypted content key corresponding to content which is specified to be protected, or to write protection information corresponding to at least part of a sectors which stores content key management file includes encrypted content key corresponding to content which is specified to be protected.

Content protection device and content protection method

A mobile communication terminal moves and backs up a content, which was downloaded from a content server, to a personal computer. When the mobile communication terminal receives an encryption key generation request from the personal computer via a cable, the mobile communication terminal extracts information to be used for generating the encryption key and generates the encryption key by using the extracted information and own telephone number. And the generated encryption key is transmitted to the personal computer via the cable. Accordingly, the backed up and moved content can be reproduced with the personal computer.

Mobile communication terminal

According to an aspect of the invention, there is provided a content sharing system including: a first device configured to acquire a right object; a second device configured to acquire a content of the right object from the first device; a session key generation unit provided in the first device and the second device and configured to generate a session key based on mutual authentication; a temporary right object generation unit provided in the first device and configured to generate a temporary right object from the right object by using the session key to supply the generated temporary right to the second device; and a content play unit provided in the second device and configured to receive the temporary right object to play the content of the right object acquired from the first device by using the temporary right object.

Content sharing system and method

This invention provides: a method for detecting SARS pathogenic viruses with high sensitivity and rapidity for diagnosing severe acute respiratory syndrome (SARS); an oligonucleotide primer that can specifically hybridize with any nucleotide sequence constructed based on the nucleotide sequence of RNA polymerase of the SARS coronavirus; a method for nucleic acid amplification using such primer; a method for diagnosing infection with the SARS coronavirus via detection of nucleic acid amplification; and a kit for diagnosing SARS.
