1. Convex type: Biti iri rinouya nemhando mbiri, sabhuku mumwe uye mukuru wembiri.Iyo yekupedzisira inonyanya kushandiswa kune yakakura-dhayamita DDP bits.
Convex DDRs inokwanisa kuchengeta mwero wepamusoro wekuchera painoboora matombo akaomarara uye akaomarara, asi kutsetseka kwekuchera kwakashata, saka haikodzere pakuchera engineering inoda kupfava kwepamusoro kwemakomba anoputika.
2, yakatarisana nemhando yemhando: iyi chimiro chechibooreso chakasimba uye chakasimba, chakakodzera kudhiraivha yakaoma uye yakaoma kwazvo dombo, asi zvakare yakakodzera kuchera gomba flatness haisi yepamusoro zvinodiwa zvepakati hard rock uye soft rock.
3. Concave type: kuguma kwechiso chebhiti musoro nechimiro ichi chine conical depression, iyo inoumbwa ne-bit mukugadzirisa kwekuchera kuchengetedza kushandiswa kwepakati kwebhiti, uye gomba rekuchera rine kunaka kwakarurama.Rudzi urwu rwebhiti rine yakanaka yekuburitsa hupfu uye nekukurumidza kuchera, uye ndiyo inonyanya kushandiswa DWB bit pamusika.
4, kuguma kwechiso chakadzika concave centre mhando: chimiro chebhiti ichi chakashanduka kubva kune imwechete mhando yebhora zino bhiti, chikamu chepakati chekupedzisira kwechiso chine yakadzika concave centre chikamu.
Iyo inoshandiswa kuita nucleation mukuita kwekuchera dombo.Pakuchera gomba rakadzika, rinogona kuve nechokwadi kuti flatness yegomba repfuti.Inokodzera chete kuchera dombo rakapfava uye yepakati hard rock.
