    • Provided are a data storage medium accessing method of accessing a data storage medium of a data storage device according to a virtual address (VA), the data storage device to access the data storage medium according to the VA, and a computer readable recording medium having recorded thereon a program to access the data storage medium accessing method. The data storage medium accessing method includes the operations of converting a logical block address (LBA) included in a command received from a host into a VA and converting the VA into a real address of a data storage medium included in a data storage device, and accessing the data storage medium using the real address, wherein the VA is an address that is based on a reserved block of the data storage medium in a data write operation, wherein the reserved block is a valid block that is ready to have data written thereto, and wherein a current location of a head included in the data storage device during the data write operation is set according to the reserved block.

    • To establish electric continuity across an actuator head suspension assembly and a pivot bearing assembly without involving an increased manufacturing cost through a simple structure. A carriage 23 made of a plastic resin is provided with a pivot opening 24. A pivot bearing assembly 30 is inserted into the pivot opening 24. The pivot opening 24 includes a step 24c formed by holes having different hole diameters from each other at an adjoining portion thereof, Two actuator arms 21, 22 are secured to the carriage 23 through insert molding to support an HDA 10. One of the two actuator arms 21, 22 is provided with a hole 24a functioning as a pivot opening and having a smaller hole diameter so as to form the step 24c. The other of the two actuator arms 21, 22 is provided with a hole 24b functioning as a pivot opening and having a larger hole diameter. The hole 24b having the larger hole diameter includes protruded portions 22a, 22b, 22c that abut against the pivot bearing assembly 30 with no clearance therebetween. The hole 24b also includes recessed portions 22d, 22e, 22f disposed between each adjoining pair of the protruded portions 22a, 22b, 22c and having a clearance from the pivot bearing assembly 30.
