Does disabling Getty stop the ability to login via ethernet over SSH?

Question

I'm currently using SSH(via ethernet cable) to login to my Raspberry pi and access it using my Laptop.(using Putty on Windows 8)

I have to use the serial port of Raspberry Pi(in GPIOs tty0) for a certain application. For that the tutorial asks to disable Getty in /etc/inittab by commenting the following line,

T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

My problem is; if I disabled "getty" will I be unable to access the Raspberry Pi using SSH? I'm a little worried as Getty is described as the program which displays the remote login screen..
