Burning Audio CD

Anyone know what is the result for causing those sa sa sound in a newly burned audio CD.

These sa sa sound only occur at the last few songs. It ranging sometimes from the 10th sometimes at the last few.

I’m try 3 type of CD. 2 of them have those sa sa sound(Samsung CDR-74S and 1 no brand type). The one which did not fail on me has a blue bottom. I’m using Wearnes 642e as my burner.

I got two suspect for it, is it the high temperature(the two which fail is both silver bottom) or those wave on the corner of the CDs.

Thanks in advance
