What are important points when designing a (binary) file format?

I am going to develop a program which will store data in file.

The file can be big. The data in the file is basically made up with variable length records. And I need random access to the records.

I just want to read some resouces/books about how to design the structure of a data file. But I can't find any yet.

Any suggestion is much appreciated.
