Exhibit 11.1

# RIMAGE CORPORATION
COMPUTATION OF NET INCOME PER SHARE OF COMMON STOCK

Basic net income per common share is determined by dividing net income by the
weighted average number of shares of common stock outstanding. Diluted net income per common share is determined by dividing net
income by the weighted average number of shares of common stock and common share equivalents outstanding, unless the result is
anti-dilutive. A total of 192 assumed conversion shares for the nine months ended September 30, 2005, and 2,969 and 10,827 assumed
conversion shares for the three and nine months ended September 30, 2004, respectively, were excluded from the net loss per share
computation as their effect is anti-dilutive. The following is a summary of the weighted average common shares outstanding and
assumed conversion shares:
