They're called Combo Drives: https://en.wikipedia.org/wiki/Combo_drive
"A combo drive is a type of optical drive that combines CD-R/CD-RW recording capability with an ability to read (but not write) DVD media; some manufacturers refer this as CD-RW/DVD-ROM drive..."
The information I can find online matches the read/write capability that's being shown.
