A method and apparatus for providing a marker at the end of the adaptive self-servowrite process for adaptive formatting via the self-servowrite process. The mark is used later in the drive manufacturing process to identify the number of tracks written on the surface and thus determine the appropriate format to use in the drive.

A method for producing sliders having positive camber on the air bearing surface. The method comprises (i) scribing the air bearing surface of a slider row along a line between individual sliders, (ii) flat plate lapping the air bearing surface of the slider row, and (iii) producing a pattern of stress on the back side of the slider row to create positive camber in each individual slider in the slider row.

A magneto-resistive (M-R) head has a read element with a servo sensing width as wide as a data track width and a data sensing width of less than one data track width. The two read sensing widths are achieved by using a single read element having a center electrical contact from the M-R read element that effectively reduces the sensing width of the read element. In a first embodiment, the servo sensing width comprises a first portion of the read element and the data sensing width comprises a second, smaller portion of the read element. In a second embodiment, the servo sensing width comprises the entire read element width and the data sensing width comprises a portion thereof. In yet another embodiment, abutting read elements are constructed to enable separate optimization of each sensing width. The wide servo sensing width permits use of a wide servo pattern having servo bursts as wide as a data track width. A position error sensing (PES) signal produced with the wide servo read element and wide servo pattern has increased linearity and accuracy.

A multi-actuator disk storage device has at least two actuators respectively mounting plural product heads. Servo writing is performed using the product heads themselves. A first servo write operation is performed that includes operating a product head of the first actuator as a first clock head to generate first clock reference information for the product heads of the second actuator, which are operated as servo write heads to perform servo writing of disk areas associated with the second actuator using the first clock reference information. To servo write disk areas associated with the first actuator, a second servo write operation is performed. This operation includes operating a product head of the second actuator as a second clock head to generate second clock reference information for the product heads of the first actuator, which are operated as a servo write heads to perform servo writing using the second clock reference information.

A station for performing a lapping method to achieve tight dimension controls for both read and write elements of magnetic recording heads is disclosed. A recording head having a read head stripe height and a write head throat height is lapped using a plurality of lapping forces. At least one of the plurality of lapping forces includes a torque force. A lapping wedge angle is controlled using at least one torque force, which controls the offset between the recording head read head stripe height and the write head throat height.

Distinct servo patterns are written on data storage media of a data storage device. Servo patterns of a first type are written for transducers of the data storage device having a first transducer characteristic. Servo patterns of a second type are written for transducers that do not have the transducer characteristic. The transducer characteristic can be a geometric criterion such as read head and write head track width, an operating characteristic such as frequency response, or otherwise. The first servo pattern may be a seamless untrimmed PES burst and the second servo pattern may be a seamed trimmed PES burst.

A method and apparatus for providing combined radial and timing multislot self-servowrite propagation is disclosed. Radial bursts are combined with each timing mark and requires only three recovery/read-write spacing allocations per sector. The channel operates without requiring the writing of any bursts between reading radial bursts.
