Problems solved by technology
When the recording position jumps, not only the corresponding position on the optical disc will have a blank recording data, but also the recorded data cannot be successfully read out in the subsequent reading, resulting in the risk of data loss

Embodiment Construction
[0024] like figure 1 As shown, it is a schematic structural diagram of an optical recording device. The optical recording device 100 includes a spindle motor 102, a motor servo driver 110, an optical head 104, an optical head servo driver 106, a servo controller 108, and the like.
[0025] The spindle motor 102 is used to drive the disc 200 to rotate. The optical head 104 is used to project a laser beam onto the disc 200 to read information from the disc 200 or write information to the disc 200 .
[0026] When recording information, the optical head 104 is also used to receive the laser beam reflected by the disc 200, and convert the reflected light into an electrical signal, which can be sent to a subsequent decoding circuit (not shown) to The information recorded on the disc 200 is obtained. The optical head 104 is also used to generate a servo error (Servo Error, SE) signal according to the reflected light, such as a focusing error (Focusing Error, FE) signal, a tracking...

The invention relates to an optical recording device, comprising an optical head used for sending out beams to an optical recording medium so as to record data in the optical recording medium and also used for receiving beams reflected by the optical recording medium and converting the reflected beams into electrical signals so as to generate servo error signals; a servo controller used for generating servo control signals according to the servo error signals so as to control the servo of the optical head; a shake detecting device used for receiving the servo error signals and comparing the servo error signals with a pre-set threshold signal so as to generate recording control signals which generate pause when the optical recording device is interrupted by external forces so as to pause the data recording of the optical recording device. The invention also provides an optical recording control method.
Description
technical field [0001] The invention relates to an optical recording device and a control method of the optical recording device. Background technique [0002] Optical storage devices, media are widely used because of their large storage capacity and low price. In the market of optical storage products, not only optical reading devices but also optical recording devices have become popular. [0003] Optical recording devices generally use a modulated light beam to irradiate the surface of an optical storage medium to record information. A typical optical recording device, such as a burner, focuses a modulated laser beam on an optical disc, and records information on the optical disc in a spiral track. A tracking servo system is provided in the recorder to ensure that the focus of the laser beam falls on the spiral track after being focused. [0004] With the increasing application of optical recording devices on various portable devices, such as notebook computers and por...
