Corporate Law: Votes of Directors

I live in a residential apartment co-op, in which I am a shareholder. The board of directors vote on various matters that come before it. Sometimes those votes are not unanimous.

I asked the board about a particular vote, which its minutes state was 6 to 1. My question was who voted against? I asked for any additional information to help me understand the reason for the dissenting director's vote.

The board replied that its policy is to not give out that information.

Can I compel the disclosure of the information?

Is the board's policy usual and/or reasonable?
