The reporting person hereby amends and restates the following items:


ITEM 3.   Source and Amount of Funds or Other Consideration

     Personal funds in the aggregate amount of $2,308,075.11 have been used to
effect the purchases.  No part of the purchase price represents borrowed funds.


ITEM 4.   Purpose of Transaction

     The reporting person continues to hold the shares for investment
purposes.

     While the reporting person continues to believe the shares are materially
undervalued, as a result of the significant percent increase in the share
price, in order to meet portfolio diversification requirements, the reporting
person has reduced his ownership level to 4.1%, from the 5.5% previously
reported in Schedule 13D filed on November 13, 2012.

     The reporting person may increase (including going back above 5%
ownership) or decrease his ownership position in the shares, going forward,
based upon the price level of the shares, in the broader context of his
investment, trading, margin, speculation, or other needs and purposes.


ITEM 5.   Interest in Securities of the Issuer

     At the close of business on January 29, 2013, the reporting person has
sole voting and dispositive power over 978,663 shares of Hutchinson
Technology's common stock.  According to the company's most recent Form 10-K,
as of December 5, 2012, there were 24,045,618 common shares outstanding.  The
reporting person is therefore deemed to own 4.1% of the company's common stock.
Such ownership level terminates any further reporting obligation under Section
13D of the Act.  Transactions effected by the reporting person, in the 60 days
prior to the January 22, 2013 "trigger" date, were performed in ordinary
brokerage transactions, and are indicated as follows:
