Description of the invention (9) In the second embodiment, it is replaced by a polymer. Therefore, the abrasive composition of the second embodiment can provide other advantages besides the advantages of the first embodiment, which will be listed later. When using the polishing composition of the second embodiment to polish the surface of a magnetic disk substrate, it is possible to avoid that the degree of polishing around the surface of the substrate is much higher than that of other portions. In the second embodiment, the polishing composition suppresses excessive polishing of the substrate around the specific surface because the polishing composition contains a polymer. The polymer reduces the friction between the substrate and the polishing pad used to polish the substrate, and functions as a compound represented by the general formula (1). It is presumed that reducing the friction will suppress the polishing of the peripheral portion of the substrate surface. When the amount of the polymer in the polishing composition of the first embodiment is greater than or equal to 0. 0.001% by weight, a polishing composition capable of sufficiently suppressing excessive polishing of the peripheral portion of the substrate surface is provided. The polishing composition also polishes the substrate surface at a sufficient polishing rate. When the amount of the polymer is greater than or equal to 0,005% by weight, it is effective to suppress excessive grinding of the peripheral portion of the substrate surface. ^ When the amount of polymer in the grinding composition of the second embodiment is less than or equal to 1% by weight, the grinding speed caused by adding too much polymer can be avoided. When the content of the polymer is less than or equal to 0.5% by weight, it is possible to more reliably avoid a sudden decrease in the grinding speed. When the polymer content is less than or equal to 0 "3" wt%, a sharp reduction in the grinding speed can be almost successfully avoided. + ^ @The artisan should understand that the present invention should have various variations without & _1¾ a month of spiritual scope. In particular, it should be understood that the present invention should be specifically described in the following forms. The first embodiment of the abrasive composition may further include
