Abstract
Tape heads are described herein including (i) a first module including a read transducer array with at least one transducer element to read data from a tape, and (ii) a second module including a read transducer array with at least one transducer element to read data from the tape. In examples herein, a lifting member is provided to cause tape lifting the module at a leading position with respect to tape travel direction.
Claims20
A tape head comprising:
- a first module including a read transducer array with at least one transducer element to read data from a tape;
- a second module including a read transducer array with at least one transducer element to read data from the tape;
- a first lifting member to cause lifting of a tape portion over the first module while the tape moves in a first direction such that the tape encounters, in the following order, the first module and the second module;
- and
- a second lifting member to cause lifting of a tape portion over the second module when the tape moves in a second direction such that the tape encounters, in the following order, the second module and the first module.

A tape drive, comprising:
- a tape head including
- (i) a first module including a read transducer array with at least one transducer element for reading data, and
- (ii) a second module including a read transducer array with at least one transducer element for reading data;
- a motorised drive for causing a tape to move in
- (a) a first direction in which the first module is at a leading position and the second module is at a trailing position, and
- (b) a second direction in which the first module is at a trailing position and the second module is at a leading position;
- a first lifting member arranged to cause a lift of a tape portion such that tape contact with the first module is prevented while the tape moves in the first direction;
- a second lifting member arranged to cause lift of a tape portion such that tape contact with the second module is prevented while the tape moves in the second direction;
- and
- a circuit to cause
- (i) the read transducer array of the first module to read data from the tape during a read operation in which the tape is moved in the second direction,
- (ii) the read transducer array of the second module to read data from the tape during a read operation in which the tape is moved in the first direction.

A method for operating a tape drive, the method including:
- moving a tape in a direction such that the tape encounters a module at a leading position and a module at a trailing position, each of the modules including a read transducer array with at least one transducer element for reading data from the tape;
- and
- reading data from the tape using the read transducer array of the module at the trailing position with respect to a direction of tape travel;
- wherein
- moving the tape includes moving the tape over a lifting member so as to cause a lift of a tape portion over the module at the leading position while moving the tape in said direction.
