The invention aims to provide a method for realizing Dex memory loading on the basis of a DexClassLoader. An apk (AndroidPackage)) reinforcement operation is carried out on a PC (Personal Computer); a reinforced application is installed, shelled, loaded and started on an Android terminal; and a reinforced dex structure is completely different from the structure of a traditional dex file and can not be successfully decompiled into a source file with readability. A reinforcement scheme successfully protects the confidentiality of key data so as to perform an anti-decompilation effect, a ZjDroil shelling tool is used for carrying out a shelling operation on the reinforced apk, and the source files and the dex fragments of any source apk can not be obtained. A memory loading process provided by the invention performs a good effect on preventing Java layer Hook, and meanwhile, a phenomenon that a dex plaintext appears on a disk and is robbed by an attacker is avoided. Compared with a traditional disk loading way, the method disclosed by the invention is characterized in that safety is greatly improved.

The invention discloses a write operation control method, system and device and a computer storage medium. The method is applied to a distributed storage system and comprises the steps that when a write request is received, a writing thread is called to segment to-be-written data into original data blocks according to a stripe mode, and the original data blocks are sent to OSD nodes for disk loading and disk unloading according to data object service OSD information corresponding to strips; a background thread is called to generate a verification data block according to the to-be-written data,and the verification data block is sent to the corresponding OSD nodes for disk loading and disk unloading. During each time of data writing, the writing thread is called to sent the to-be-written data to the data lower disk only, then the background thread is called to asynchronously calculate the verification data block, and then independent disk loading and disk unloading are carried out. Thebackground thread does not work on an IO path of a service lower disk, the data amount of the lower disk of the service IO path is reduced, and in this way, the time delay of each time of data writingis reduced so that the distributed storage system can provide higher performance, more paths of video stream services can be supported, and customer requirements can be met.

A disk loading for loading either a first or second, smaller, disk. The disk loading device comprises a main chassis, a power transmission unit, a slider, a first and second linkage mechanism, a sub-chassis, and a locking lever. The first linkage mechanism guides the first disk to a chucking position while being pushed and moved by the first disk, and moves the slider in connection with the power transmission unit when the first disk is being introduced. The second linkage mechanism connects the slider to the power transmission unit while being pushed and moved by the second disk when the second disk is moved to the chucking position. The sub-chassis is linked to a guide unit which separates the first linkage mechanism from the first disk or the second disk placed on the chucking position. The locking lever selectively locks the movement of the first linkage mechanism or releasing the locking of the first linkage mechanism.

The present invention relates to a disk recording and/or reproducing apparatus in which a disk-like recording medium such as an optical disk is transported between a disk loading portion for recording and/or reproducing information and a disk entrance and exit slot into and from which the disk-like recording medium is inserted and ejected. The disk recording and/or reproducing apparatus includes a pair of transport rollers which can hold the disk-like recording medium in the diametrical direction and a drive means for rotating a first transport roller of the pair of transport rollers and wherein a second transport roller of the pair of transport rollers is fixed and the drive means rotates the first transport roller to rotate the disk-like recording medium by rotation force so that the disk-like recording medium is transported between a disk loading portion for recording and/or reproducing information and a disk entrance and exit slot. Users can transport the disk-like recording medium, between the disk loading portion and the disk entrance and exit slot by only touching the outer peripheral edge of the disk-like recording medium in the diametrical direction. Therefore, when the disk is transported, since no members contact with the signal recording surface, a foreign matter can be prevented from being pressed against the signal recording surface, a foreign matter can be prevented from damaging the signal surface and hence an information signal can be read and written with high reliability.

A disk loading apparatus is provided which stops disks, even if the disks have different diameters, when disk center holes have been ejected to the substantially same positions out of an apparatus body during the ejection. The disks can be pulled out without soiling a recording surface of the disk. One disk-pass detecting switch detects a pass of the last end of each disk and discriminates sizes of the disks. In addition, a rotation time of a roller after the detection of the pass is controlled depending on disk diameters.
