[0002] Designers of traditional optical disc drives generally pre-burn some optical discs on the market to determine the writing strategy (Write Strategy) for burning different optical discs, such as: burning power, burning time and burning position, but due to the There are many types of CDs, so some small-scale manufacturers cannot pre-test all CDs to determine the burning strategy of different CDs. Even because some CDs are produced later than CD drives, CD drive designers cannot get CDs in advance discs to determine the burning strategy of these discs
However, without pre-testing and adjusting the optical discs, the optical disc drive does not have a corresponding burning strategy to burn these optical discs, so the optical disc drive can only use the general burning strategy to burn optical discs, and therefore the users of the optical disc drive It is often encountered that the burning condition of the CD-ROM is not good, the quality is not good, and it cannot be read back.

Embodiment Construction
[0032] In order to make the above and other objects, features, and advantages of the present invention more comprehensible, the preferred embodiments are specifically listed below, together with the accompanying drawings, and are described in detail as follows:
[0033] FIG. 1 is a schematic diagram showing a programmer 100 according to an embodiment of the present invention. The burning device 100 includes an optical disc 110 , a laser source 120 , a light detection chip 130 , a high-pass filter 140 , an optical module 150 and a burning control device 160 . The high-pass filter 140 includes a resistor 142 and a capacitor 143. The capacitor 143 is coupled to the input terminal V of the high-pass filter 140 in and the output V out between. The resistor 142 is coupled to the output terminal V of the high-pass filter 140 out and a reference voltage V ref between. When the burning device 100 pre-burns the optical disc 110 to determine the burning strategy, the laser source 12...

A burn-recording adjustment method is used for adjusting a burn-recording power, a burn-recording time and a burn-recording position of a burn-recorder, the burn-recorder is provided with an optical detecting chip for receiving a reflected optical signal and converting the optical signal into a burn-recording detection signal to be transmitted to a high pass filter, the high pass filter receives the burn-recording detection signal and outputs a filtering signal. The burn-recording adjustment method comprises burn-recording a first short period data on an optical disk, obtaining a reference voltage of the high pass filter according to a first maximum and a first minimum of the filtering signal, burn-recording a first mixed period data on the optical disk based on a plurality of predetermined burn-recording times, and using a result operated from the first maximum, the first minimum and the reference voltage as a target value according to the first maximum and the first minimum obtained from the filtering signal and a first burn-recording power adjusting and determining the burn-recorder.
Description
technical field [0001] The present invention relates to a programming adjustment method, in particular to a programming adjustment method for adjusting the programming power, programming time and programming position of a programmer.
