The scope of the invention The present invention is related to the cat dish, and the media storage area in Zuanxian County is used to record the format. "Mei Jing Technology Catalog" used in the disk drive + .. Ai Chou film is formatted in many different ways depending on the saved servo information and data. One of the most common formats used in conjunction with a magnetic disk with multiple disks is a dedicated speech surface. In this configuration, ~ Magnetic > {specially used to save high-frequency vocabulary information, this information is temporarily stored in Gujing's reading records {Zjg 立 &》 "Ziguto is continuously kept on the track (track temporary storage), This reward can also be used to find new track positions. Another common format is to design servo information and data segments for single or multiple word service sector segments. In the single-word service sector segment format, the magnetic disk "Mu-Fu The track or magnetic column has a single shelf as a word service shelf, and a _ shelf as a data block. In the format with a multi-word service sector, there are Xufu palms separated by magnetic disks' each combined with one or several data columns . The word guards on each track are similar to the data shed, and are arranged in a radial direction. This type of word guards is extremely flexible, and it simplifies the functions of centering or magnetic heads. On behalf of the Central Ministry of Economy For quasi-bureau printing f, please read the precautions on the back before filling in this page} • The shortcoming of the line and item configuration method is that the storage data space is not effectively used. Generally speaking, the same amount is stored on the inner and outer tracks Data. Therefore, the transition density on the outer orbit is much smaller than that on the inner As a result of the change in density on the track, the recording energy of the off-disk drive cannot be used. Recently, the format of Ou Kaiji Ga has been used internationally. This format makes each track or magnetic branch into two The above concentric areas, such as the outer storage area, one or more intermediate storage areas and an inner storage area. Each of these areas contains Xu Jia 4 (210Χ 297 Gongshou) 199931 V. Multi-storage data sector, each λ Generally speaking, the external storage is divided equally between the sections near the orbit.-The staggered storage area in the middle has the most equal-heavy segment sectors. The extension has the least equidistant segment sectors. One segment .: Storage ⑷ favorable Because, from the most # 胃 & & to ... this configuration is extremely good, the amount of data changes, and \ circle: Dao ... Ye can be included in the most. However, this configuration buys the storage capacity of the disc drive disk. The starting point of the shape segment is jealous. The shortcomings of Lang Zang, the first fan in each track can be different, and they can assist in the search of the magnetic heads across the regions. Therefore, this configuration is very important for the word service information. It is inconvenient for ye shang xun to obtain j evil things on the whole ruling.

The frequency of the gallium is greater than the middle = the sector segment data of the outer storage area is the storage frequency of the segment storage data of the intermediate storage area. The recording frequency of the segment data shed is issued twice: Another purpose is to provide non-jumping fan segments in the intermediate storage area and the inner storage area by generating a recording gap between the fan segment after each ⑫ track C jump and the index indicator Spacers' on the inner gap is greater than the intermediate track referred KK KK performed track mind the gap. The area of the slewing memory media of the drive _ service sector format adjustment scheme includes the external memory storage area containing the pre-selected number of external data tracks and the internal memory storage containing the pre-selected number of internal data tracks. Area. Each external data has a pre-selected number and I has servo information and data. Each inner data track has a pre-selected number of inner sectors with servo information and data. The number of fan-shaped segments outside each track is different from the number of inner segments in each track. In addition, the selected outer sector segment and the selected inner sector segment define many radial adjustment indexes according to the radial adjustment. Another aspect of the present invention is that each outer sector segment has an outer word service and an outer data block 'and each inner segment has an inner word service block and an inner data block. The information recording rate of the internal data block is the same as the data on the external data block, and the internal servo block is the same as the data. The external data is low. The other aspect of the invention is the external fan shape. Duan are done along each outer track (please read the precautions on the back of the moraine before filling out this page).

Magnetic: Γ 步 说 ’The applicant ’s assignee has developed another type of class machine, which allows magnetic pieces to be magnetically coupled or physically connected to thorium. ^ Gongshen,% Daxiang, ', Kou (❹U.S. Patent filed on the 14th in the detailed year: No. 27〇, 948 and No. 270, 〇5 filed in the US Patent Application on the W_year) If it is a structure of magnetic coupling rather than physical connection, there is a space between the king axis motor and the axis of the magnetic piece. In this magnetic coupling configuration, because there is no direct connection between the spindle motor and the magnetic plate, there is some flexibility between the magnetic plate and the main sleeve motor. It is important to understand that the feedback directly from the main sleeve motor is usually not sufficient to ensure the stability of the magnet rotation. Due to the existence of irregularities in the potential for interactive rotation, the single servo and single-index feedback from the magnetic body are not sufficient to provide control as stability. Therefore, each turn must have multiple feedback. Therefore, the present invention provides multiple simultaneous feedback in each area of the magnetic disk containing the storage area recording scheme.
