[edit] 1 Data.Binary

There are a number of binary I/O libraries available for Haskell. The best to use is the new, semi-standard Data.Binary library:

   * Data.Binary

It's very simple to use, and provides a highly efficient, pure interface to binary serialisation.

For just writing binary data to file, use

   * System.IO

It is a part of the base package, so it comes with GHC.

A tutorial:

   * Serialisation and compression with Data Binary

See also Dealing with binary data

[edit] 2 Other libraries

For very simple serialisation, use
read
and
show
.

If you have simple binary IO requirements, then Data.ByteString might be easiest -- you get a List-like interface to packed byte arrays (interface documented here). For more complex serialisation, Data.Binary would be preferred.
