file / string problem?

I new to python and I'm having a problem writing a binary string to a
file.  I'm using the zipfile.py module and getting the data from the
zip file and writing it to a file object.  The string returned from
the zipfile.read() function is the correct size, but when I write it
to disk, the file on the disk is the wrong size and corrupted.  Any
ideas?  Do I have to do something special with binary data in strings?

Code:

import zipfile

z = zipfile.ZipFile('D:\\tmp\\esbdates.zip')
try:
	# read the binary data into a string
 	 S = z.read('esbdates.hlp')
	# note len(S) here returns 362588 which is correct  as per 
	# zipfile.py AND winzip
	f = open('D:\\tmp\\esbdates.hlp', 'w')
	try:
		f.write(S)
	finally:
		f.close()
		# file size is 365,452 bytes!
finally
	z.close()

Python 1.5.2
Platform: Win NT 4.0 SP 5  

thanks,
