                                  SCHEDULE 13D

Preliminary Statement

This filing by Laitram, L.L.C. (sometimes called the "Reporting Person") amends
a Schedule 13D filed by The Laitram Corporation on March 25, 1999. Only the
amendments to the Schedule are reproduced below. This statement relates to
equity securities of Input/Output, Inc. ("I/O").

James M. Lapeyre, Jr. is the President and chief executive officer of the
Reporting Person. He is also a director of I/O and Chairman of its Board of
Directors. As a director of I/O, Mr. Lapeyre may take an active role in
corporate strategy and business decisions involving I/O. The Reporting Person
(and its predecessor, The Laitram Corporation) have elected to file this
Statement on Schedule 13D rather than Schedule 13G as a precautionary measure in
case Mr. Lapeyre's actions in his capacity as an I/O director are attributed to
the Reporting Person or should the Reporting Person, as a shareholder of I/O, be
a participant in a transaction involving I/O. The election to file on Schedule
13D shall not be deemed an acknowledgment or admission by the Reporting Person
that the actions of Mr. Lapeyre are attributable to the Reporting Person, and
the Reporting Person hereby disclaims any such actions by Mr. Lapeyre. The
election to file on Schedule 13D shall not be deemed an acknowledgment or
admission by the Reporting Person that such a statement is required to be filed
pursuant to ss. 240.13d-1(e), or otherwise, or that the Reporting Person holds
securities of I/O with a purpose or effect of changing or influencing the
control of I/O, or in connection with or as a participant in any transaction
having that purpose or effect. The election to file on Schedule 13D shall not be
deemed an acknowledgment or admission by the Reporting Person that the Reporting
Person does not continue to be eligible to file a statement on Schedule 13G,
pursuant to ss. 240.13d-1(c), as a person who, among other things, has not
acquired such securities with any purpose of, or with the effect of, changing or
influencing the control of I/O, or in connection with or as a participant in any
transaction having that purpose or effect.

ITEM 1. Security and Issuer

The class of equity securities to which this statement relates is the common
stock, $0.01 par value per share (the "Common Stock"), of I/O, a Delaware
corporation, whose principal executive offices are located at 12300 Parc Crest
Drive, Stafford, Texas 77477.

ITEM 2. Identity and Background.

This statement is filed on behalf of Laitram L.L.C., a Louisiana limited
liability company. The information required to be reported under this Item 2
with respect to each executive officer, manager and controlling person of
Laitram, L.L.C., and each officer and director of Laitram Group, Inc., the
parent company of Laitram, L.L.C, is set forth in Schedule A attached hereto and
incorporated herein by reference.

Laitram, L.L.C. is a successor of The Laitram Corporation. Through a series of
transactions that occurred on September 30, 2002 and December 31, 2002, The
Laitram Corporation was



CUSIP No. 457652105                                          Page 5 of 13 Pages

reorganized as an S Corporation for tax purposes, Laitram Group, Inc. was formed
to be the holding company for The Laitram Corporation, and The Laitram
Corporation was reorganized as a limited liability company called Laitram,
L.L.C. Laitram Group, Inc. is the sole member of Laitram, L.L.C., and all but
one of the former shareholders of The Laitram Corporation are now instead the
shareholders of Laitram Group, Inc. The proportionate ownership of each
shareholder of The Laitram Corporation prior to these transactions generally was
the same as the proportionate ownership of each shareholder of Laitram Group,
Inc., following the transactions, except for the effect of the one shareholder
who is entitled to receive cash for her shares of The Laitram Corporation rather
than shares of Laitram Group, Inc., and except that the proportionate ownership
of several shareholders increased slightly because they contributed additional
capital to Laitram Group, Inc.

Laitram, L.L.C.'s principal business is acting as the parent holding company of
four wholly-owned subsidiaries which design, manufacture and sell industrial
products. Laitram, L.L.C.'s address and the address of its principal office is
220 Laitram Lane, Harahan, Louisiana 70123.

During the last five years, neither Laitram, L.L.C. nor its predecessors nor, to
the best of its knowledge, any of the persons listed on Schedule A hereto has
been (a) convicted in a criminal proceeding (excluding traffic violations or
similar misdemeanors) or (b) a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction as a result of which any of them
was or is subject to a judgment, order, 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.

Each of the individuals listed on Schedule A hereto is a citizen of the United
States.

ITEM 4. Purpose of Transaction.

On March 26, 2003, Laitram, L.L.C. distributed 1,002,956 shares of I/O Common
Stock as a dividend to its sole member, Laitram Group, Inc., which immediately
thereafter distributed the 1,002,956 shares as a dividend to its shareholders,
prorata. Certain of the shareholders of Laitram Group, Inc. who received shares
of I/O, including Messrs. James M. Lapeyre, Jr., G. Charles Lapeyre, Philip F.
Lapeyre, Robert S. Lapeyre and Andrew B. Lapeyre, and Mrs. Monique Lapeyre
McCleskey, all of whom are listed on Schedule A hereto, have agreed that for a
period of three years, they will not sell the I/O shares they received in the
distribution without the written consent of the majority of the parties to the
agreement, voting in proportion to their ownership of the distributed shares.

Laitram, L.L.C., continues, as did its predecessor, The Laitram Corporation, to
hold Common Stock of I/O as an investment. Subject to market conditions and
other factors deemed relevant to it, Laitram, L.L.C., or any person named on
Schedule A attached hereto or in Item 5 hereof, may purchase, directly or
indirectly, additional shares of I/O Common Stock or dispose of some or all of
such shares in open market purchases or privately negotiated transactions.

Mr. Lapeyre, the President and chief executive officer of Laitram, L.L.C., is a
director of I/O and chairman of its Board of Directors. The actions of Mr.
Lapeyre in his capacity as an I/O director



CUSIP No. 457652105                                           Page 6 of 13 Pages

and chairman of its Board of Directors may be attributable to Laitram, L.L.C. In
such case, Laitram, L.L.C. may be deemed from time to time to consider plans or
proposals relating to, or may be a participant, as a shareholder of I/O, in a
transaction involving: the acquisition or disposition of securities of I/O;
extraordinary corporate transactions involving I/O or any of its subsidiaries;
selling or transferring a material amount of assets of I/O or any of its
subsidiaries; changing the present board of directors or management of I/O;
materially changing the present capitalization or dividend policy of I/O; making
other material changes in I/O's business or corporate structure; changing I/O's
charter, bylaws or instruments corresponding thereto or other actions which may
affect control of I/O; causing the I/O Common Stock no longer to be quoted on
the New York Stock Exchange; causing the I/O Common Stock to become eligible for
termination of registration pursuant to Section 12(g)(4) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"); or taking any action
similar to any of those enumerated above.

To the best knowledge of Laitram, L.L.C., each of the persons named on Schedule
A attached hereto, other than Mr. Lapeyre who has filed a statement on Schedule
13D that speaks for itself, acquired the shares of I/O Common Stock reported
herein as beneficially owned by such person for purposes of investment and not
for the purpose of changing the control of I/O.

Other than as described in the original Schedule 13D filed by The Laitram
Corporation or in this amendment, neither Laitram, L.L.C. nor, to the best of
its knowledge, any of the persons named on Schedule A attached hereto (other
than Mr. Lapeyre who has filed an amended statement on Schedule 13D that speaks
for itself) has any plans or proposals that relate to or would result in any
actions set forth in Item 4 of Schedule 13D relating to I/O or shares of I/O
Common Stock.
