Abstract

In one general embodiment, a system includes a first device on a first substrate; a second device on a second substrate; and a device select system coupled to the first and second devices. The device select system includes: a first portion having an array of first electrical contacts; a second portion having an array of second electrical contacts, there being more second electrical contacts than first electrical contacts, the second portion being coupled to the first and second devices, each of the first electrical contacts being associated with at least two of the second electrical contacts; and a select mechanism for selectively placing each of the first electrical contacts in electrical communication with one of the second electrical contacts associated therewith.

Claims

1. A data storage system, comprising:

a first array of transducers on a first substrate of a first module;

a second array of transducers on a second substrate of a second module, the first and second modules each having a planar media bearing surface;

a device select system in electrical communication with the first and second arrays,

the device select system comprising;

a first portion having an array of first electrical contacts;

a second portion having an array of second electrical contacts, there being more second electrical contacts than first electrical contacts, the second electrical contacts being in electrical communication with the first and second arrays, each of the first electrical contacts being associated with at least two of the second electrical contacts; and

a select mechanism for selectively placing each of the first electrical contacts in electrical communication with one of the second electrical contacts associated therewith;

a flexible cable electrically coupled to the first portion of the device select system;

a drive mechanism for passing a magnetic recording medium over the head; and

a controller electrically coupled to the cable.

2. A system as recited in claim 1, wherein the first and second electrical contacts and select mechanism are formed in a common structure.

3. A system as recited in claim 1, wherein the select mechanism includes an array of switches, the array being for selectively placing each of the first electrical contacts in electrical communication with one of the second electrical contacts associated therewith.

4. A system as recited in claim 1, the second array being positioned relative to the first array to allow transduction of data to and/or from a same side of the magnetic medium, and further comprising an actuator for controlling a position of the first and second substrates relative to a recording medium, the device select system moving with the first and second substrates relative to the recording medium.

5. A system as recited in claim 1, further comprising at least one third electrical contact on the first portion and being in electrical communication with the select mechanism for passing control signals thereto.

6. A system as recited in claim 1, wherein the first and second substrates are coupled together, wherein the first and second substrates together form at least a portion of a magnetic tape head.

7. A system as recited in claim 1, wherein the first array is an array of multiple reader transducers and/or an array of multiple writer transducers on the first substrate, wherein the second array is an array of multiple reader transducers and/or an array of multiple writer transducers on a second substrate, the select mechanism selectively placing the first electrical contacts in electrical communication with the first array of writers or the second array of writers.

8. A system, comprising:

a first array of devices on a first substrate;

a second array of devices on the first substrate;

an actuator for moving the first and second array in a cross-track direction during operation of the first and second arrays, the cross track direction being perpendicular to longitudinal axes of data tracks on a magnetic medium passing the arrays of devices; and

a device select system coupled to the first and second arrays of devices, the device select system comprising;

a first portion having an array of first electrical contacts;

a second portion having an array of second electrical contacts, there being more second electrical contacts than first electrical contacts, the second portion being coupled to the first and second arrays of devices, each of the first electrical contacts being associated with at least two of the second electrical contacts; and

a select mechanism for selectively placing each of the first electrical contacts in electrical communication with one of the second electrical contacts associated therewith,

wherein each of the first and second substrates has a planar media bearing surface.
