Patent number: 5812338Abstract: A disk and a disk drive having a servo start mark for identifying a servo-information start position recorded on the disk is provided. The servo start mark has a plurality of bit patterns unused for other areas in servo information. A method for identifying the position of a signal transducer on a disk is also provided in which it is judged that the signal transducer is present at a predetermined position even if an error is present and the error is a one-bit error. This is accomplished by assuming that the position is correct when the following conditions are confirmed: (a) a parity error occurs in a read servo-information bit pattern and (b) read servo-information bit pattern does not coincide with servo information of an adjacent track.Type: GrantFiled: May 17, 1996Date of Patent: September 22, 1998Assignee: International Business Machines CorporationInventors: Kenji Ogasawara, Takashi Nakamura, Nobuya Matsubara, Yuzo Nakagawa, Yuji Kigami, Hiroshi Uchiike, Tsutomu Numata

Patent number: 5809042Abstract: An improvement in an interleave type error correction method in which more errors can be corrected with less correction codes is provided. Array patterns of code words constituting the information code is form by interleaving. The array patterns comprise a plurality of sequences of a plurality of code words. Correction codes are added to the sequences so that a total number of the correction codes added to a selected sequence is greater than a total number of the correction codes added to the other sequences. An error correction is executed in the selected sequence by identifying a position of an error as a consecutive error code position, when the selected sequence is determined to contain said error having a characteristic feature that the error extends over other sequences. A code word of a position corresponding to said consecutive error code position of the selected sequence among code words in the other sequences is recognized as an erasure.Type: GrantFiled: April 12, 1996Date of Patent: September 15, 1998Assignee: International Business Machines CorporationInventors: Akio Nakamura, Masayuki Murakami, Tsutomu Numata

Patent number: 5625840Abstract: A programmable external storage control apparatus, including a buffer for temporarily storing data to be transferred between a host and an external storage, which stores a program for controlling data transfer between the host and the external storage and controls the data transfer between the host and the external storage by reading the data transfer control program from the buffer and executing it. The apparatus further includes a microprocessor that responds to a command from the host by starting the control of the data transfer by reading the data transfer control program. The microprocessor includes a memory for storing the data transfer control program in addition to other programs to be executed by the microprocessor. The microprocessor loads the data transfer control program from the memory into the buffer at the time of initialization. This allows the microprocessor to do other jobs such as servo control while the data transfer control program is executed.Type: GrantFiled: April 13, 1995Date of Patent: April 29, 1997Assignee: International Business Machines CorporationInventors: Tsutomu Numata, Yuji Kigami, Tatsuya Sakai, Kenji Shimizu

Patent number: 5561566Abstract: A disk drive having embedded servo information accesses data without using sector identifier recorded in each sector. When a signal sector pulse signal (SP) at the end of a servo area is detected in a dead state during start up, a first data state for the start of a sector transits to a second data state for the litter region of the sector being divided in accordance with the capacity stored in a current sector's pointer register. At the beginning of the sector, the contents of a next sector's pointer register is stored in current sector's pointer register and the contents of a next sector's operation register is stored in a current sector's operation register. Upon completion of sector processing, the first data state is maintained when the next sector is contiguous. When a terminate instruction is stored in current sector's operation register, the process moves to dead state. When the servo area arrives, the process moves to idle state.Type: GrantFiled: December 15, 1994Date of Patent: October 1, 1996Assignee: International Business Machines CorporationInventors: Yuji Kigami, Koji Kurachi, Takao Matsui, Takashi Nakamura, Tsutomu Numata, Kenji Ogasawara, Mayumi Okada, Yuji Yokoe
