The present application relates to the technical field of data storage backup, and especially relates to a method for seamlessly recording audio and video based on a double-disc embedded system. Step S1, cache the audio and video information to be recorded; Step S2, load disc A; Step S3, record; Step S4, periodically detect the memory occupation ratio and adjust the corresponding parameters to the corresponding values; Step S5, continue recording disc B and calculate the audio information similarity of disc A, and adjust the corresponding running parameters of the recording unit to the corresponding values during the recording process of disc B according to the similarity; Step S6, send a termination signal to complete the recording. Compared with the prior art, the present application has the beneficial effect that during the recording process of disc A, the central control unit periodically detects the memory occupation ratio in disc A, and adjusts the corresponding parameters to the corresponding values according to the detection results, thereby ensuring the completeness of the recorded data and the recording effect.

The invention provides a method for obtaining compensation CD deviation of a mask, the mask and an etching pattern, and belongs to the field of semiconductors. The method for acquiring the compensation CD deviation of the mask comprises the following steps: providing an ion implantation layer; based on the actual measurement values and the deviation of the first distance and the second distance, establishing a curve of the deviation of the test pattern changing along with the first distance and the second distance; acquiring actual measurement values of the first distance and the second distance of the target pattern in the active region and the isolation region; and based on the changing curve and the actual measurement values of the first distance and the second distance of the target graph, obtaining the CD deviation value of the mask of the target graph. According to the invention, the offset is compensated to the actual design size of the mask, and after the mask is exposed in an actual product, the accuracy of the critical line width CD of the photoresist can be improved, and the phenomenon of photoresist collapse is improved.

This utility model discloses a CD storage box, including a box body with evenly spaced slots inside. Each slot contains a placement box containing a CD. A fixed plate is rotatably connected to one side wall of each slot. The placement box has a semi-circular structure, with a follower plate at one end that extends and retracts into the fixed plate. A linkage plate is rotatably connected to the edge of the placement box away from the follower plate. Multiple slots are provided inside the box, allowing for the storage of multiple CDs. Each CD has an individual cover for closing, preventing the removal of one CD from affecting the others. Lifting the corresponding cover allows the linkage plate to pull one end of the placement box up, causing it to rotate and rise along the connection with the follower plate, tilting outwards for easy removal of the CD. Protective pads protect the CDs from wear and tear and prevent them from being thrown out by inertia.
