Is the remote control function of cd player using cdm2 optical head universal?

I stopped watching the disc in the middle, and I stopped watching it. I don't know why. At first, I thought it was a bald head problem, but the current of the optical head was 54MA, which didn't look like aging. I got angry after I didn't get better for a long time. I happened to have a few idle M4 bald heads, so I implemented a long-planned plan to replace the CDM4 with CDM2. Who knows, the replacement was successful and the reading was normal. Later, the parameters on the servo board were changed, and there was basically no problem. Later, it was moved to Philips' CD player, and the disc was read normally without any problems.

There is an antique machine, marantz CD65IIse, which is said to be the highest signature version, with a typical 72 10 servo+154 1 decoding. In short, it was cheated, and something went wrong within two days after it was brought back. The reading speed of CD is very slow and the playing noise is very loud. After changing the optical head, the problem remains the same, and then all kinds of tossing, changing Philips axial electrolysis, changing crystal oscillator, checking power supply and adjusting the optical head. The current situation is that reading discs is better than before, but the noise problem is still serious, that is, squeaking, even higher than music. But the strangest thing is that most discs are noisy, but there is a series of four discs that are not noisy.
