	(c), (f)		Attached as Exhibit 99.A is information, including name and citizenship, concerning each executive officer and director of each of the Reporting Persons. Exhibit 99.A is incorporated into and made a part of this Schedule 13D.

	(d), (e)		Other than as described above, during the last five years, none of the Reporting Persons or, to the best of the knowledge of the Reporting Persons, any of the persons listed on Exhibit 99.A attached hereto, has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or was or is a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which such person was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws, or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration

Effective August 1, 2007 (Japan time), the Reporting Persons received 6,825,764 shares of common stock of Imation pursuant to an Acquisition Agreement entered into by Imation and TDK, a Japanese corporation, on April 19, 2007, providing for the acquisition by Imation of substantially all of the assets of TDK’s business relating to the marketing, distribution and sale, including customer service and support, of removable recording media products, accessory products and ancillary products under the TDK brand name (the “TDK Recording Media Business”), including the capital stock of TDK’s operating subsidiaries engaged in the TDK Recording Media Business.

The purchase price for the TDK Recording Media Business was approximately $261 million, plus or minus certain post-closing price adjustments, and plus potential earn-out payments over the course of the next three fiscal years of up to an aggregate of $70 million. The $261 million consideration paid to TDK consisted of Imation common stock having a value of approximately $231 million and approximately $30 million in cash. 6,825,764 shares of Imation common stock, valued at $33.91 per share and representing approximately 16.6% percent of the outstanding shares as of July 31, 2007, were issued to TDK by Imation from treasury.

Item 4. Purpose of Transaction

The acquisition of the securities referred to herein is for the purpose of TDK’s investment in Imation. The transaction makes TDK the largest shareholder of Imation, and gives TDK a right to nominate a representative to serve on the Imation Board of Directors.

Pursuant to an Investor Rights Agreement entered into by TDK and Imation, dated July 31, 2007, (i) TDK is permitted to increase its ownership of Imation common stock up to 21% of Imation’s outstanding common stock through open market purchases, (ii) TDK received certain preemptive rights and registration rights, and (iii) TDK agreed to a standstill on further acquisitions of Imation common stock above the 21% threshold (except as a result of stock repurchases initiated by Imation, in which event TDK’s ownership is not permitted to exceed 22% of the then outstanding shares). The Investor Rights Agreement also includes a voting agreement with respect to certain matters presented to Imation stockholders and a three year lock-up on sales by the Reporting Persons of the Imation shares acquired in the transaction. TDK anticipates increasing its ownership of Imation’s common stock to over 20%, but less than 21%, of Imation’s outstanding common stock, through one or more additional purchases as permitted by the Investor Rights Agreement, prior to the end of March 2008.

In connection with the investment and transaction described herein, TDK and Imation also entered into two Trademark License Agreements and a Supply Agreement. Under the two long-term Trademark License Agreements, dated July 31, 2007, which TDK will have the right to terminate at the end of 25 years (10 years in the case of

headphones, speakers or wholly new products) or earlier in the event of a material breach of the Trademark License Agreement, change of control, divestiture or default by Imation, TDK licensed a TDK trademark to Imation and one of its subsidiaries. One of the agreements licenses the trademark to Imation for the U.S. territory, while the other licenses the trademark to an Imation affiliate outside the U.S. The trademark licenses provide Imation exclusive use of the TDK LIFE ON RECORD logo for marketing and sales of current and successor magnetic tape, optical media, and flash memory products, certain accessories, headphones and speakers, and certain future removable recording media products. Under the Supply Agreement, dated July 31, 2007, TDK agreed to supply Imation’s requirements of removable recording media products and accessory products for resale under the TDK brand. TDK will continue its manufacturing operations for recording media products including audio, video and data storage tape, and Blu-ray optical discs, which TDK will supply Imation as well as its other OEM customers.

Other than as described herein, the Reporting Persons have no present plans or intentions which relate to or would result in any of the transactions required to be described in Item 4 of this Schedule 13D.

The descriptions of the transactions and agreements set forth in this Schedule 13D are qualified in their entirety by reference to the complete agreements governing such matters, each of which are incorporated by reference into this Schedule 13D as exhibits pursuant to Item 7 hereof.

Item 5. Interest in Securities of the Issuer

TUC, TEC, TES, TRE, THK and TSP are all wholly owned subsidiaries of TDK. TDK has sole dispositive and voting power over 4,047,390 shares of Imation common stock held directly by TDK and shared dispositive and voting power over 2,778,374 of the shares of Imation common stock held by the other Reporting Persons. TDK is the beneficial owner of 100% of the shares of Imation common stock cumulatively held by the Reporting Persons. TDK is a Reporting Person with respect to shares of common stock of Imation held for the account of TDK.

See Items 7-13 of each cover page.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

In connection with the transactions described herein, (i) Imation and TDK entered into the Acquisition Agreement, pursuant to which TDK has acquired the shares of Imation common stock, and (ii) Imation and TDK entered into the Investor Rights Agreement, pursuant to which Imation has provided TDK with certain rights, including, but not limited to, the right to nominate a representative to serve on the Imation Board of Directors, preemptive rights and registration rights.

Except as otherwise described herein, no contracts arrangements, understandings or similar relationships exist with respect to the securities of Imation between the Reporting Persons and any other person or entity.

Item 7. Material to Be Filed as Exhibits

	1.		Acquisition Agreement, dated April 19, 2007, by and between Imation Corp. and TDK Corporation (incorporated by reference to Exhibit 2.1 to the Current Report on Form 8-K filed by Imation on April 25, 2007).
