Derry has said that he is determined to bring some stability back to the League One outfit.
"That stat is there for a reason and I'm not worried," he told Sky Sports News.
"It's a club that's not found the right balance and hopefully I am the kind of guy who is going to bring stability and a bit of enjoyment to the fans here because it's been an up and down time for Notts County fans in recent years.
"I remember very well the time I was supporting here and watching Neil Warnock and the great strides he made for Notts County. I am not saying I'm going to replicate that by any stretch of the imagination but what I can do is say that I am going to give absolutely everything for this club and myself."
Derry's first match in charge will be Saturday's FA Cup first-round tie against Hartlepool United.
