I am trying to call a helper class in magento but stuck with an error message from magento.

The helper class is located at

app/code/core/Mage/Catalog/Helper/Product/Compare.php

The class name is 

class Mage_Catalog_Helper_Product_Compare extends Mage_Core_Helper_Url

I tried the below call

$helper=Mage::helper('catalog_product_compare');

Error message I got

Fatal error: Class 'Mage_Catalog_Product_Compare_Helper_Data' not found in C:\xampp\htdocs

How can i call this helper class?
