## CPC

- G11B 33/08: Insulation or absorption of undesired vibrations or sounds
- G11B: INFORMATION STORAGE BASED ON RELATIVE MOVEMENT BETWEEN RECORD CARRIER AND TRANSDUCER (recording measured values in a way that does not require playback through a transducer G01D9/00; recording or playback apparatus using mechanically marked tape, e.g. punched paper tape, or using unit records, e.g. punched or magnetically marked cards G06K; transferring data from one type of record carrier to another G06K1/18; circuits for coupling output of reproducer to radio receiver H04B1/20; gramophone pick-ups or like acoustic electromechanical transducers or circuits therefor H04R)

## Abstract

An apparatus and method reduce the transfer of vibration to and/or from a data a data transfer mechanism in a data storage device by coupling an adaptive mount responsive to an electrical stimulus to the data transfer mechanism. In one embodiment of the invention, a controller reads a signal that relates to the position error of a read/write component in a data transfer mechanism, applies an algorithm, and varies the damping of an adaptive mount coupled to the data transfer mechanism. The controller may be further configured to report an error to a host system that identifies a substandard data transfer mechanism so that such data transfer mechanism can be repaired or replaced.

## Claims

### Claim 1

A data storage device comprising:
a data transfer mechanism, and
an adaptive mount coupled to the data transfer mechanism and configured to dampen the transfer of vibration at least one of to and from the data transfer mechanism in response to an electrical stimulus, and wherein the adaptive mount includes an electrorheological (ER) fluid.

### Claim 2 (depends on 1)

The data storage device of claim 1 wherein the adaptive mount further includes electrodes.

### Claim 3

A data storage device comprising:
a data transfer mechanism, and
an adaptive mount coupled to the data transfer mechanism and configured to dampen the transfer of vibration at least one of to and from the data transfer mechanism in response to an electrical stimulus, and wherein the adaptive mount includes a magnetorheological (MR) fluid.

### Claim 4

A data storage device comprising:
a data transfer mechanism, and
an adaptive mount coupled to the data transfer mechanism and configured to dampen the transfer of vibration at least one of to and from the data transfer mechanism in response to an electrical stimulus, and wherein the adaptive mount includes an electrostatically stricted polymer (ESSP).

### Claim 5

An apparatus comprising:
a structural member configured to support a data transfer mechanism; and
an adaptive mount coupled to the structural member and configured to dampen the transfer of vibration at least one of to and from the data transfer mechanism in response to an electrical stimulus, and wherein the adaptive mount includes an electrorheological (ER) fluid housed in a capsule.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein the adaptive mount includes electrodes.

### Claim 7

An apparatus comprising:
a structural member configured to support a data transfer mechanism; and
an adaptive mount coupled to the structural member and configured to dampen the transfer of vibration at least one of to and from the data transfer mechanism in response to an electrical stimulus, and wherein the adaptive mount includes a magnetorheological (MR) fluid housed in a capsule.

### Claim 8

An apparatus comprising:
a structural member configured to support a data transfer mechanism; and
an adaptive mount coupled to the structural member and configured to dampen the transfer of vibration at least one of to and from the data transfer mechanism in response to an electrical stimulus, and wherein the adaptive mount includes an electrostatically stricted polymer (ESSP).
