The types of recordable DVDs that can be used are limited depending on the type of DVD recorder or DVD drive device.
In particular, it should be noted that there are many devices that can use only one of DVD-RAM and DVD-RW, DVD-RW and DVD + RW (recently, devices that can use all recordable DVDs are also on sale).

In addition, there are some devices that can use DVD-R but cannot use CPRM compatible DVD-R. In addition, a single-sided dual-layer DVD requires a device that supports recording. Regarding this point, the type of DVD that is compatible with the instruction manual of the device is specified, so please check here.
