Crystalline forms of diazabicyclooctane derivative and production process thereof

A process for preparing a diazabicyclooctane compound represented by the following formula (I): wherein A represents RcO—; B represents NH or NCalkyl; C represents a benzyl group; Rc represents a Calkyl group; A is substituted with one substituent Fn1, wherein Fn1 represents an azetidine group; the process including: (a) silylating the compound represented by the following formula (IV-c): wherein in the formula (IV-c), OBn represents benzyloxy, and (b) carrying out an intramolecular urea formation reaction.

Processes for preparing a diazabicyclooctane compound

According to embodiments, a magnetic disk device includes a magnetic disk, a magnetic head, and a controller. In the magnetic disk, a plurality of servo sectors is arranged in a circumferential direction. Servo information including a post code indicating a repeatable runout (RRO) correction amount is written to each of the plurality of servo sectors. The magnetic head writes and reads data to and from the magnetic disk. In positioning control for the magnetic head, when a read error of a first post code continuously occurs, the controller uses a first RRO correction value, which is different from a second RRO correction value based on the RRO correction value indicated by the first post code. The first post code is a post code of a first servo sector, which is one of the plurality of servo sectors.

Magnetic disk device and method

A controller provides a plurality of first sections with numerical information on a first scale. The plurality of first sections are obtained by dividing a recording surface of a magnetic disk in units of first memory areas in each of which a first volume of data can be written by an SMR method. The first scale corresponds to a sequence of the first sections. The controller provides a plurality of second sections with numerical information on a second scale. The plurality of second sections are obtained by dividing the recording surface of the magnetic disk in units of second memory areas in each of which the first volume of data can be written by a CMR method. The second scale corresponds to a sequence of the second sections. The controller executes a plurality of commands in order based on a numerical information on the first scale or the second scale.

A process for preparing a diazabicyclooctane compound represented by the following formula (I): wherein A represents RcO&#x2014;; B represents NH or NCalkyl; C represents a benzyl group; Rc represents a Calkyl group; A is substituted with one substituent Fn1, wherein Fn1 represents an azetidine group; the process including: (a) silylating the compound represented by the following formula (IV-c): wherein in the formula (IV-c), OBn represents benzyloxy, and (b) carrying out an intramolecular urea formation reaction.

According to one embodiment, a first storage area and a second storage area in which a plurality of tracks are set are provided in a radial direction of a magnetic disk. A plurality of post codes corresponding to the second storage area is stored in the first storage area. A controller controls first processing of reading a plurality of post codes from the first storage area and writing the plurality of read post codes in servo area of the second storage area. In the first processing, the controller controls both second processing and third processing in a state where a write head is located on a first track. The second processing is processing of writing a post code among the plurality of read post codes in a servo area. The third processing is processing of writing user data in a data area or reading user data from a data area.

A crystalline form I of a compound represented by Formula (VII-1): having characteristic peaks appearing at lattice spacing (d) of 7.34, 5.66, 5.53, 5.30, 5.02, 4.66, 4.37, 4.28, 4.06, 3.68, 3.62, 3.47, 3.36, 3.30, 3.16, 3.11, 3.03, 2.99 and 2.50 &#x212b; in the powder X-ray diffraction pattern.

According to an embodiment, a magnetic disk device includes a magnetic disk including a first storage area and a second storage area different from the first storage area. In the second storage area, both of a first post code that is used to write user data in the first storage area by a first method and a second post code that is used to write user data in the first storage area by a second method are stored in advance. The first method is a method in which one track between two tracks adjacent to each other overlaps a part of the other track between the two tracks. The second method is a method in which two adjacent tracks do not overlap each other.
