I presume you have got a point shape file which you want to turn into raster. There is an arcmap 10 tool Point to Raster(Conversion) that should do the job. You can set raster cell size and output raster image format, ie, .tif, .img etc.

More info can be found under the following link: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00120000002z000000

Hope that helps!
